Hello ! Please, help me! I have a very good computer ,but twinmotion crashes too often...

Hello! I use the Twinmotion 2023 .1.2 + Archicad 26 (11 windows).

Until recently, everything was fine - everything worked on ultra settings (my 4090 and 13900 K certainly work good). I started uploading fbx furniture models there from different resources. But for some time now departures have begun - sometimes in real time I twist the model, the picture freezes, the mouse, everything crashes and an error window from Unreal engine is issued.

887A0006 - error code. I have already set the minimum graphics settings, dug into the nvidia settings - it does not help. Anyway, at some random moment departure. I tried switching from direct x 12 to 11 - then yes, it doesn't crash, but I can't render anything. And I have updated Direct x 12. And it does not fly out of path tracing, namely real time. I have already run it on behalf of the administrator.... deleted, reinstalled... nothing works. Sometimes I have to open a project, do not touch anything for 20 minutes, and then slowly, slowly it begins to work.. But then another crash again... (sorry for my bad English)312
