twinmotion 2026 direct x 12 problem

Weird problem here. If TM is set to use direct x 12 then it will crash fairly quickly at random and every single time when saving (losing all of my work). The error message says it’s looking for files on my D drive. I don’t have a D drive. This is the message:

Fatal error: [File:D:\build\TM+20261\Sync\Engine\Source\Runtime\D3D12RHI\Private\D3D12Util.cpp] [Line: 1030]
Result failed
at D:\build\TM+20261\Sync\Engine\Source\Runtime\D3D12RHI\Private\D3D12Viewport.cpp:572
with error 80004004
Viewport=0x000001CEA35667C0, Num=3, Size=(3840,2054), PF=18, DXGIFormat=0x18, Fullscreen=0, AllowTearing=1

If I set TM to use direct x 11 then it works OK but the functionality of TM gets gutted.

Windows, bios, video driver, etc. are all up to date.

Lenovo Legion 9, 64 GB ram, nvidia 5090 video card.

Anybody have any ideas?

Thanks in advance
