UCEERR_RENDERTHREADFAILURE
Why is this happening?
This error is usually caused by an issue with your video card (graphics) drivers or Windows itself. The app relies on your graphics card to help draw the interface quickly and smoothly — but if your drivers are out of date, corrupted, or something goes wrong during startup, it can cause the graphics system to crash behind the scenes, leading to this error.
What can I do about this?
Update your video card drivers
Go to your video card manufacturer’s website (like NVIDIA, AMD, or Intel) and download the latest drivers. This fixes the issue in most cases.Run Windows Update
Sometimes this kind of issue is fixed by Microsoft in a Windows update. Make sure you're fully up to date.Restart your PC
It sounds basic, but if something weird happened during startup, a reboot can reset the graphics system.
