Hi there, I’m Arlene, an independent advisor, here to help.
This error usually means your graphics card driver crashed or was stopped by Windows. Even if it's updated, I recommend doing a clean reinstall using Display Driver Uninstaller (DDU) in Safe Mode, then reinstall the latest official driver from NVIDIA or AMD (not beta). Also, try turning off hardware-accelerated GPU scheduling in Windows and make sure you're not overclocking your GPU. Microsoft points out that these steps often help with the DXGI_ERROR_DEVICE_REMOVED issue.
Hope that helps, feel free to reply to this message if you need further assistance.
Regards,
Arlene D.
