I opened Unity for the first time in a while today and I'm unable to create new scripts of any type. Both the normal and right click menus are missing the option:
Adding a script through the inspector creates a file, but yields these errors:
Although the file is created, it does not appear in either the project browser, or inspector panels.
Googling various parts of these errors actually gets a lot of posts, but almost all of them come down to "restart Unity", which isn't doing anything.
All of this is reproducible for me on a fresh project file. I've tried restarting Unity and my computer, as well as reinstalling Unity from scratch. I've also double checked that I have .NET installed properly (reinstalled, and dotnet command works in terminal).
Unity: 5.4.5p5
Mac OS 10.13.3
This is a bug present in versions between Unity 5.1 and 5.4. It has been fixed in Unity 5.5.0 and an update to 5.5.0 and above should fix it.
If updating to Unity 5.5.0 which has the fix did not fix it then it's better to upgrade Unity to the latest version which is currently Unity 2017.4 at the time of posting this answer. This version should be able to get ride of that error.

About a week ago I opened shader graph in one of my projects when I noticed the connections between nodes are just gone (like shown in the image). The shader still works just fine as if the connections are there, but it's impossible to work with since they are not visible. Today I have noticed that the Visual effect graph also lacks the connections. The problem started on Unity 2021.3.6f1, then I upgraded to Unity 2022.1.22f1 and the problem remains. Even if I create a new project I still can not see any connections. I am working on Macbook pro 2017. Any help would be appreciated.
shader graph without connections
I tried restarting computer, reinstalling Unity Editor, downgrading to an older version of Unity Editor and creating a blank project but nothing fixed the problem.
I experienced this same issue in Unity 2021.3.11f1, and confirmed the bug in multiple projects that were previously fine (only one of which was recently changed).
What MacOS version are you running? My best guess is that MacOS Ventura 13.1 broke some versions of Unity, as upgrading from macOS Monterey was the biggest change to my system this week (2019 MacBook Pro 16").
The following steps appear to have resolved the issue for me (so far so good):
Reboot the computer (just to be sure)
Backup the project (I just created an archived duplicate)
Install Unity 2021.3.16f1 (the latest LTS release)
Delete the project library (in case there's something weird cached)
Open the project in the new version of Unity (which also regenerates the library)
I am now able to edit shader graphs again. Of note, deleting the library and regenerating in 2021.3.11f1 did not fix the issue. Only opening it and regenerating the library in 2021.3.16f1 worked for me.
I did not test leaving the old library intact while opening the project in the newest LTS version of Unity; it's possible regeneration isn't necessary, but it does seem like the safest bet. Especially if you didn't try removing the library before upgrading the project to Unity 20221.22f1 and you're still experiencing issues. You might try deleting the library to see if that resolves the issue now, without trying to downgrade to 2021.3.16f1?
There's a post over on the Unity Answers support site about this issue as well, but the login system appears to be broken (the irony!), so I can't respond there. https://answers.unity.com/questions/1927887/shader-graph-connections-not-visible.html
I have a problem in development of mixed reality app and there has been 2 days that I'm stuck.
My problem is that after adding packages of MRTK to the unity project, if I click the play button, the unity exits (closing) without any error massages or warning.
I tested two versions of unity (2020.3.32f1 and 2020.3.33f1) and both had the same problem.
I am using this link (MRTK document) and also this one Mixed Reality Feature Tool as a guide for configuration and adding the packages of MRTK to my project.
I have also tried two different versions of the packages i.e. (Mixed Reality Toolkit Foundation and Mixed Reality Toolkit Extensions both versions of 2.7.3 and 2.7.2 and for Mixed Reality OpenXR Plugin package I tried 1.4.0 and 1.3.1 versions).
I am using Visual Studio 2019 version 16.11.14
Inside Unity, I am choosing Universal Windows Platform from the Build Settings and I want to practice a little development of mixed reality applications, but I am stuck at the beginning and when ever I press the play button the unity exits (closed) without any warning or error.
Just for more information → I don't have Microsoft Hololens2, therefor I am considering to use Windows Mixed Reality simulator (Mixed Reality Portal).
I can't get what mistakes I am doing, please if you have any idea help me.
Thanks in advance.
There are many steps to configure a Unity Project for Mixed Reality. According to the description, it is hard to determine which step causes the issue. I have created a repository which is implemented with the necessary MR packages, and the configuration has been done. Feel free to pull the repo from https://github.com/sethdu0525/MR-Blank-Project. Please open it and click run to test.
If you still have this issue, you may need to have a clean installation of Unity 2020.3.33f1 (LTS), Visual Studio 2022 and make sure all the required components have been installed, including a comparatively new Windows SDK.
If you have a dump file for the crash, you may also share it and find support from Unity forum -- General Discussion - Unity Forum
I am facing a problem with unity 3d editor. The issue is in both the versions of the Editor that I have downloaded being 2021 version and 2019.4 version. It occurs whenever I create and load up a new project in the unity editor.I have made no changes in the script or the scene so it is probably a problem with the packages. The module I have downloaded is the android build support and windows build support. Moreover I do not get any error message. I am attaching a screenshot. Please check the screenshot and please see what is the problem. Please help is you can. I will be very thankfulPlease see the picture and Help
When I launch a project via Unity Hub, the following message is printed : Unity is already in list. You cannot locate the same version.
unity hub error
And when I want to access my project via Assets -> Scenes.
I get this : error message
If I said "continue", my project is broken with a lot of errors to fix.
Have you a solution ?
Thanks
From what I see in your screenshot, you are trying to open a project with an older unity version than the project's version. As it is written in the message, the operation is not supported and you should open it with at least the same version, or an older one. Make sure you have such a version installed in Unity Hub and to open the scene with this version.
You can still try to get everything to work by reimporting all you assets in Assets -> Reimport All but this will probably fail.
I have installed latest version of unity(5.6.0f3) from https://store.unity.com. Every time i try to launch the unity I get unity bug reporter window popped up.I am not able to create a new project or use unity. I uninstalled latest version and installed unity 5.3.5f1 version. But still I am facing the same problem.
Maybe memory problem in your pc, try to end task of anything running even google chrome (because it takes a lot of memory) and then run Unity as administrator.
It can be also that your windows is 32 bits and you wanna run Unity3d 64 bits.
I hope this helped you ;)
I also faced the problem like this.
In my case this bug reporter appeared when I tried to open the "unity-3d-simplefps-master" project downloaded from GitHub.
So I renamed the source folder name and I just avoided this bug reporter.
Best wishes!
