[Metal] [iOS] GPU Execution of the command buffer was aborted due to an error during execution

Metal

-

Reproduction steps:
1. Open the project from the drive (info for access in edits ctrl+f "access" (size is above 20GB extracted))
If the project import is stuck on one step (for more than 30 mins), force-quit Unity and try opening the project again
2. Open "ProductionScene.unity"
3. Switch platform to iOS (might take up to 2 hours)
4. Go to OPTION_NAME (Edits) -> GameConfigs and enable "AI Takeover"
5. Go OPTION_NAME (Edits) -> BuildConfig
6. At the bottom of the window press "Set Scripting Defines for iOS Development"
7. Once it indicates that it is completed press "Build iOS Development"
8. Once it finishes building Xcode will be launched automatically (project will be generated .. /PROJECT_NAME)
9. Deploy the project to an iOS device
10. In Game enable "Full Dev Menu"
11. Disable "Use Front End"
12. Press "Play"
13. Cars will be automatically driving for 2 laps (you might be asked to "log in" if launching for the first time, just continue with the tag generated)
14. If the freeze does not occur re-launch the application and repeat steps 10-13

Unexpected behavior: at some point the application freezes, "Execution of the command buffer was aborted due to an error during execution" errors are thrown in the console

Reproducible with: 2020.1.15f1
Could not test with 2021.1.0a8 (errors related to Input)

Devices tested:
VLNQA00310 iPad Pro 12.9 1st gen (iOS 13.4.1) (Freeze rate 3/15)
iPhone 12 (iOS 14.2) (Freeze rate ~1/10)
iPhone XS (iOS unknown) (Freeze rate 6/11)
iPhone 12 Pro (iOS unknown) (Freeze rate 1/11)

Notes:
1. It is very hard to do steps 10, 11 because of the small UI size
2. The project is basically impossible to update to another stream without errors because of the size and the asset/package count

  1. Resolution Note (2020.1.X):

    This bug will be addressed as part of the ongoing DOTS effort and will addressed before the 1.0 release of DOTS
