Twinmotion - Several version crash on launch

Hi everyone,

Every Twinmotion version since 2023.1.2 crashes on a PC/WIN on launch through the Epic Games Launcher.

No crash logs are created since above version. Updates up to 2025.1 haven’t brought an improvement.

Launching project files doesn’t work as well. De-installing, re-installing and verifiying hasn’t helped.

The large pink button goes “Launch” > Click “Busy”, “Running” > “Launch”. That’s all.

I have a relativ strong PC with 13th Gen Intel(R) Core™ i9-13900KF 3.00 GHz, 64 GB RAM and WIN 11 with RTX 3080.

Any idea where I could start searching for the reason.

Thanx!
