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
#1739

https://github.com/user-attachments/assets/d5e36a95-7efa-4edf-a7b7-805d1ce5b338

I think it's related to vulkan

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:

vulkan validation layers enabled.txt
