Twinmotion crashes and deadlocks after enabling dx12

Hello everyone. Wanted to try pathtracing on my msi laptop, and despite warnings about possible technical difficulties after that, desided to risk it. Now it crashes after a minute of work, I cant switch back to DX11 - after restart it continues to set dx12 in prefs. Tried reinstalling, didn't help. Found configs in MyDocuments, there s nothing about DX at all. If someone had faced that issue, please help.
