Unity build only shows a gray screen - unity3d

I'm making a multiplayer first-person shooter, in the editor, I can play fine but when I build it, it just shows a gray screen and nothing happens. unity doesn't show any error after building.
i'm using unity 2020.1.6f1 and HDRP + DRX
my pc specs are:
AMD Ryzen 5 2600 Six-Core Processor
Nvidia GeForce GT 1030
this is the main menu in the editor
this is the build, it should show the main menu

You can try enabling Development Build from build settings to access the development console in the standalone application. Alternatively you can check the log files for the application for any errors that only happen in the build.
Based on current documentation you can find the log files from:
Windows: %USERPROFILE%\AppData\LocalLow\CompanyName\ProductName\Player.log
Mac: ~/Library/Logs/Company Name/Product Name/Player.log
Linux: ~/.config/unity3d/CompanyName/ProductName/Player.log

Failed to start Vuforia on Unity UWP executable build

I'm trying to build a very simple UWP app (for PC Desktop only) with a single image target and camera using Vuforia on Unity.
Everything works fine in the Editor, but after I build and run the app I get the following error on a black screen :
I don't even know where to debug this, as the only log I get is this error and nothing else. I also tried delayed initialization, but this same behavior happens when I manually call VuforiaAppllication.Instance.Initialize(); after it's initialized and before it's started.
Here's my build settings :
I'm using Unity 2020.3.30f1 and Vuforia 10.2.5, the only target SDK installed on my system is 10.0.19041.0 and also, I have Visual Studio 2019 Community installed if that info helps.
Fixed by disabling my laptop's webcam from device manager, and connecting an external USB camera.

Unity+ARToolKit: rendering error in windows application

I use the Unity 5.6.0f3 (Personal Edition) + ARToolkit (v5.3.2) under Windows 10 Home SL. I choose the PC,Mac,Linux option from build settings. I load the default example scene from ARToolkit package (Examples->Scenes->FisticuffsScene) and launch it. I have got that render problem
Why do some of the model parts not be rendered? Can anyone help me?
In case of build settings for android everything is rendered fine.

Unity3D error Fix [duplicate]

I want to use c++ dll on unity android application. To use native dll on a android device, I learn that I should use Unity 5. I download unity5 from here. My application requires vuforia. So I download vuforia package from here.
Unity 5 is 64 bit.
On unity editor, I delete MainCamera and add ARCamera. There is an error message on unity console. The message is below :
Failed to load 'Assets/Plugins/QCARWrapper.dll', expected 64 bit architecture (IMAGE_FILE_MACHINE_AMD64), but was IMAGE_FILE_MACHINE_I386.
Vuforia.WebCamAbstractBehaviour:CheckNativePluginSupport()
There is a solution for this problem on vuforia forum. But I don't find unity editor(32 bit)
To use Vuforia with Unity 64 bit, just move the QCARWrapper DLLs from /Plugins to /Plugins/x86. These are the DLLs:
QCARWrapper.exp
QCARWrapper.lib
QCARWrapper.dll
QCARWrapper.dll.signature
This should solve the problem!
Go to https://unity3d.com/get-unity/update Under there, you will see ADDITIONAL DOWNLOADS Under that you will see FOR WINDOWS. Click it and choose Unity Editor (32-bit).
EDIT:
I see lots of dowvotes. This was the ONLY solution when this question was asked. Unity 5 64bit just got released when this question WAS asked and this was the ONLY solution back then. This answer was changed to the current answer that was provided 5 months later when Vuforia released 64bit version of their plugin.
Vuforia 5.0 supports the 32bit version of the Unity Editor on Windows, and the 64bit version on Mac.
So, There are two possible solutions:
you just need to install and use the Unity 5 32bit Editor, on Windows.
OR
Create a new folder "x86" inside
Assets>>Plugins
inside your unity project structure
Then move the following files from "Plugins" to newely created "x86" folder.
QCARWrapper.lib
QCARWrapper.dll
QCARWrapper.dll.signature
QCARWrapper.exp
After that check log message, If you see the log like:
Setting platform to 'Editor' for plugin: Assets/Plugins/x86/VuforiaWrapper.dll
UnityEngine.Debug:Log(Object)
Vuforia.EditorClasses.ExtensionImport:UpdatePluginSettings() (at Assets/Vuforia/Editor/Scripts/ExtensionImport.cs:43)
UnityEditor.EditorApplication:Internal_CallUpdateFunctions()
Then , Congrats !! You are ready to Go!
I had the same problem /Failed to load 'Assets/Plugins/QCARWrapper.dll'/ with vuforia plugin and latest version of Unity ( currently 5.1.2f 64bits ) and also couldn't get my laptop camera to work.
Everything is fixed with the 32 bit release of Unity, even if my os is 64 bits (Windows 7).
If you are using Unity 5.1, make sure to set the right Graphics API settings in the Player Settings for Android and iOS:
disable the "Automatic Graphics API" checkbox
in the Graphics APIs list, make sure that only OpenGL ES 2.0 is included:
Android: remove OpenGL ES 3.0
iOS: remove OpenGL ES 3.0 and METAL
Important :
1. In your Unity project:
Select the QCARWrapper.bundle in the Unity Project view (located under Assets > Plugins ), so that its settings are shown in the Unity Inspector
Change the settings of QCARWrapper.bundle in the Unity inspector from "Any Platform" to "Standalone + Editor".
Rebuild
​OR:
In the Xcode project generated by Unity:
Go to Build Phases > Copy Bundle Resources
Remove the QCARWrapper.bundle file from the list
Rebuild
My unity3d version is 5 and 64bit
,Os is Windows7 64 bit.
my Problems solved .
Edit :
Unity editor couldn't show laptop camera ,But Rebuild Project , camera work .
for example rebuild Android platform , and install .apk on device => application Ok .
Go to Name_Vuforia_Unity_Project\Assets\Plugins and you will find QCARWrapper.dll.
Delete it and try again (could be necessary to restart unity).
