Unity UI button not reacting to clicks or hovering - unity3d

I'm using Unity 3D's new UI system to build a pause menu for my game. Currently I'm trying to have my buttons respond to mouse clicks. Some of my hierarchy is as follows:
When I click on one of my buttons in-game nothing happens, this includes a lack of button animation that should occur when hovering. My "Main Canvas" gameobject contains the following components:
I have already ensured that my Image component has "Raycast target" checked and that my Button component has "Interactable" checked.
Could this be because my Canvas' render mode is in screen space (camera)? I need the render mode to be set to this because I have 3D models that are added in front of the UI during gameplay.
Things I have already tried / checked:
Ensured that an EventSystem was present
Checked that another UI element wasn't covering the buttons, preventing a raycast
Ensured that the camera rendering the UI is above my main camera that is attached to the player. The rendering UI camera has a layer of 1 while the player camera has a layer of 0.

Your EventSystem GameObject is missing the Standalone Input Module Script component.
Select your EventSystem->Add Component ->Standalone Input Module. Done!
The gif below decsribes two ways to do that.

If anyone here ever runs into this problem and none of these fixes work, go to Edit > project settings > Input, then in the inspector tab click the little gear icon in the top right corner and click Reset. this should fix all your buttons!

Ensured that EventSystem component is present in the hierarchy. Without EventSystem unity is not able to track any events that's occurring in the particular scene

Try to change short order in canvas. Maybe the button canvas is blocked by another canvas.

If anyone here ever runs into this problem and none of these fixes work:
Chose your button in Hierarchy -> Find "Canvas" in Inspector -> Delete IT(Remove component)!

If you´re using the InputSystemPackage go to Edit > ProjectSettings > Input System Package. And in supported devices make sure there´s a Mouse option, if not, press the + button below and add the mouse device.

If you are pausing the game by setting the timescale to 0, then no input will work if the update mode of the input system is set to process events in Fixed Update, since the fixed update is not run at zero timescale - you can change the update mode in Edit > ProjectSettings > Input System Package.

For me it was because the button was covered by other components in the Canvas. I changged put the button in the very front whithin the campus, and it works now

Please check for the "EventSystem" to be present in Hierarchy to make button working.
refer the attachment for it

I had this same problem in Unity v2020.3.24f1, and after trying all suggestions to no avail I noticed in my case the Graphic Ray-casting was un-checked. Just in case somebody tried everything and is still facing this issue, make sure it is ticked in the canvas element!.

Had a similar issue, my event system already had the Standalone Input Module attached and I apparently followed the warning and replaced it with Input System UI Input Module which broke mouse events. Adding the standalone Input module back isn't enough, the other input module must be disabled or removed. So try using the Standalone Input Module exclusively in your event system.

Msft MRTK3 on Unity for HoloLens 2 - Object Manipulator feature overrides button clickable/pressable functions. Why?

I am trying to design a UI panel using MRKT3 for the HoloLens 2. It is a panel with pressable buttons. Anytime I add object manipulator script (to make panel grabbable, interactable, etc.) this unfortunately seems to make my buttons no longer clickable.
How can i go about this?
Inspector with Object Manipulator included
For the issue reported, what is likely happening is the button is getting the parent attributes applied via inheritance. From the image, one cannot see the code or relationship but that is what sounds like in the post.
If you have the pressable button to be the parent and underlying objects under it, that should work.

Unity UI Resume Game button is unclickable

So i have been trying to create a pause menu for my project, however the resume button is un-clickable (the same i believe for another button on this menu). The event system does not show anything when hovering over this button or attempting to click it.
Screenshot of Event System not showing button object
The button itself is set to interact-able and has the button's image as it's target graphic. The canvas it is also placed on also has the Graphic Ray-caster component attached. I also do not believe that there is any UI object covering the button preventing it from being clicked.Screenshot of Pause Menu UI as seen from scene view to show no blocking objects I am making use of the first person character controller starter asset by unity as well as the new input system.
I am unsure as to what could be causing this, I have also tried locking the cursor of the starter asset inputs.
Any advice would be greatly appreciated.

My button Not responding on Hover or Click in Unity 2D UI

Ok as you read title you will know problem. The problem is very old and much people tell fixes. But nothing works for me. So please help another time. I have EventSystem in hierchy. See picture

My EventSystem in inspector
Panel of buttons in Inspector
And finally button in inspector(These 2 images for buttons because button in inspector is some long).
If you need more Info right below and I will edit the post. Thanks for your help
I had a similar issue of not being able to engage with a button. The reason being there was another UI component with ray cast enabled that did not allow inputs to reach the button.
For your case, I think it's the "The things...". Try disabling that and see if you can engage with the button again.
I had a similar issue, where I couldn't see button interactions in a scroll view. I eventually created a click event (which worked) to find the source of my problem. While it wasn't a Raycast problem, someone else might find this handy (or I will see it in the future!)
Mine (an issue I've accidentally 🤦‍♂️ created in the past) was that I set the color of the attached Image component to black and couldn't see the interaction states in the Button. So to restate, leave Image.Color white/opaque but change button states if you want dark menus.

UNITY button onClick not working in mobile but working fine in pc

I have made some actions on clicking a button in unity.It is working fine while I am running it in unity simulator,but not working in mobile.I have also given functions to the button while onClick.But its not working.
Check if you have activated the Mobile Input on the toolbar, if yes then look if in your scene have a EventSystem (if not, right click on hierarchy and create one), at least, if the problem continues please show us the code of the function that its called when press the button. we cant solve a problem that cant see.

Unity new UI button click able outside of button area, non clickable over button area

I have created new UI button in empty scene,
Whenever I click on button its not click-able , but when I take cursor slightly above the button area and click, it gets clicked.
I guess Something like offset problem occurring?? Any fix to that?
NOTE I have tried creating new scene same result
,also created new project though Same result.
Did you check the EventSystem gameObject, it displays which UI element you are hovering, and other useful information.
After lot of trial and errors, reinstalling Unity did the job
