[Backport] [Linux] Editor crashes at "GfxDeviceGLES::DrawBuffersBatchMode" when entering Play Mode in the LEGO tutorial

--

-

How to reproduce:
1. Open the user attached project (My project.zip)
2. Make sure the "LEGO tutorial" scene is open
3. Enter Play Mode
4. Observe the crash

Reproducible with: 2021.3.2f1
Not reproducible on: 2022.1.0f1, 2022.2.0a12
Couldn't test with: 2019.4.38f1, 2020.3.34f1 (Compiler errors due to the tutorial project and its packages being incompatible with the used version)

Reproducible on Ubuntu 20.04
Not reproducible on Windows 10

Note: the project also crashes on 2022.2.0a12 but there is no stacktrace and since the issue is not reproducible on 2022.1.0f1 which indicates that that is likely a different bug

Last five lines of the crash stacktrace:
#0 0x00555a4fc66a0c in burst_signal_handler(int, siginfo_t*, void*)
#1 0x007fda210503c0 in funlockfile
#2 0x00555a5020026a in GfxDeviceGLES::DrawBuffersBatchMode(GfxBatchHeader const&)
#3 0x00555a4fb9b18a in ScriptableBatchRenderer::RenderMultipleMeshes(RenderNodeQueue const&, RenderMultipleData const&, VertexInputMasks)
#4 0x00555a4fb9cfd7 in ScriptableBatchRenderer::Flush(BatchBreakCause)

    By adding "-force-vulkan" as a command line argument for a project, I was able to run my project without Unity crashing.
    Seems that this issue is related to: https://issuetracker.unity3d.com/issues/linux-editor-crashes-at-assert-fail-base-dot-cold-when-opening-a-project?page=1#comments
    Although, I'm using official Nvidia drivers and not mesa drivers.

    I have a project with just a few simple materials that crash with the same error, with: 2021.3.8f1, and 2021.3.11f1. Ubuntu 22.04.1.
    I have reported the issue(IN-18856) but by bug report has been closed and marked as a duplicate of this one.
    Looks that this is the same issue: https://issuetracker.unity3d.com/issues/linux-editor-crashes-at-gfxdevicegles-drawbuffersbatchmode-when-entering-play-mode-in-the-lego-tutorial

    The other one is marked as resolved: "Fixed in 2022.2.0a17".
    I don't understand how such basic problem is not being fixed for 6 months already. It's making Unity 2021.3 unusable with Linux. Does Unity give up on Linux support?
