Hello ,
Thank you for posting in the community and reporting back on what you did to resolve the issue. It is interesting that the power limit was causing the crash typically adding a TdrDelay in the registry helps avoid this type of crash based on this article:

Regarding the MSI Afterburner, that application installs Riva Tuner which is the application causing crashing if running but they have a beta (7.3.4 Beta 6 Riva Tuner) release currently that avoid the crashing issue. Here is the article to reference on the MSI afterburner crash:

We look forward to helping improve those GPU related crashes with future version of Twinmotion and please report crashes and bug directly by using the [ contact us ] button from the home page or by following this link:
