This is really strange and it could be also the HW issue as it is happening directly after application opening. What are the machine’s parameters?
This issue might be connected to some really old files located in the C:\Program Files\Capturing Reality
Please try to uninstall RealityCapture then head to C:\Program Files\Capturing Reality and delete everything you will find about RealityCapture also in ProgramData, AppData, and Windows registry. Then restart your PC and try to install RealityCapture again and run the same test.
