I assume these capture one register itself for some codes, or whatsever and MSFS is simple a windows game 
Heres as example a similar issue, where these tool let crash the explorer:

where a user mentioned the same solution as the OP mentioned:
Problem is solved!
You need to rename the file in the path C: \ Program Files \ Capture One \ Capture One 20 \ WIC \ WIC64
P1.WIC.NativeComWrapper.dll to the name P1.WIC.NativeComWrapper.old
Works! Explorer does not crash!
May be these explorer integration can be in meanwhile disabled within that tool, if these was the reason.
