It might help, if you create scan exclusions in Defender for the trainer exe file and a file called ~Mnn133.tmp which is located in the Windows Temp folder here -> C:\Users\YourWindowsUserName\AppData\Local\Temp\
Best thing to do is to keep Defender disabled for this as Defender would flag the file immediately again.
Once done, clear Defender's quarantine and scan history, the Windows Temp folder as well, reboot your PC and launch the trainer with admin rights again.
That is one of the very few files that MUST be added to exclusions of your anti-virus and Windows defender. Just add the entire path you posted to your exclusion list.
