Launching from Reallusion Hub would not work no matter what I tried. I tried restarting, reinstalling, and running as administrator. Switching to Windows 8 compatibility mode worked.

The FAILURE_BUCKET_ID from the crashdump was "STACK_OVERFLOW_c00000fd_CharacterCreator.exe!Unknown". I uploaded the .dmp file to Claude, Opus 4.7 to see if it could trace the reason (it thinks it has to do with my multi-monitor setup and a negative Y-offset). I had it output the conversation as a PDF and I've attached it on the off chance that you can get any useful information from it (ignore the first question, I had uploaded the RLLauncher log file before I found the actual .dmp).
