Can you re-upload the log after turning on Vulkan Validation Layer in the emulator?
This has a high similarity to the problem I'm having

I've just updated to latest main and can confirm these issues have been solved.

@hgh32 here are the logs if you're still interested, I've enabled the Vulkan Validation Layer as you requested:
