Scenes not running in Linux builds for specific project

Hello.

I have a commercial game which I've been trying to make work for Linux. However, any Linux build that I make isn't working with any scene from the project.

The result is always: I can see the splash screen, then the game transitions to a dark blue background and freezes there.

I tested very basic/clean scenes (just camera or just camera + small UI) that use almost no memory, but still doesn't work.

I tested opening new projects then building, and that works! Which probably means the problem is a setting in my project. I tried changing the graphics API settings and the build's compression method for example, to no results.

Any potential fixes for my project?

Here's the setup:
- Building usingUnity 2020.1.5f1, running on Windows 10
- I'm testing on a Ubuntu 20.04.1 LTS virtual machine provided by Windows' Hyper-V solution
- The virtual machine properly runs other projects

Result (after Unity logo splash screen):

 

Here is an update. I found that the scene IS running, just not rendering anything.

Vulkan isn't supported in my VM, so it forces OpenGL as the Graphics API.

Here is the OpenGL log.

Hey, thanks for answering. In this screenshot, the full game is included with all the scenes, it is same version that I published successfully for Windows. I also tried to just build simpler scenes from this same project, but none of them work and show as if it was an empty scene.

It appears as an empty scene because, for some reason, the OpenGL graphics API is not rendering anything that I try to put in the scene. Thus, it just shows the Unity background.

I just haven't found out why that is happening.

 

Yes, I did that and they do get printed. The time scale is running as normal.

But nothing gets rendered. I haven't been able to test with Vulkan yet because it's not supported in the Virtual Machine, but OpenGL is supported and doesn't render anything.
