Ok, so here comes my daily update π
I have enabled Windows Sandbox and tried Fences in there, that worked
I have used the "Purge_Fences.bat" and removed Fences completely, followed by a restart
I have disabled all non-ms services and startup tasks/ apps (The Clean boot)
I have installed a fresh, crash!
I have turned both Mandatory and Random ASLR off for the app, the restarted, crash
I have uninstalled with the bat file, restarted, left the custom ASLR rules and tried to reinstall, crash
So when all Windows security features are turned on and on the latest 20H2 build 19042 Fences crash (for me)
These are my settings:

The same Event Log from above is reported every time the app crashes.
