[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
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
