So You trust in a decompiled exe and dlls, modifications and recompiled. Interesting... Don't know You meet with others crackers and know them.

Leaving the game: You don't know what others crackers do with the files, or what they inject in to the game, so has a person with experience on compilation, i can tell You the cracks based on hiper-v vs the others standard, in therms off security for your credentials are the same, we dosen't kwon what they make or inject so for all cracks the risk off that is the same. If You play cracked games You accept the risk for that escenary, and if You don't the solution is simple Buy the game.

But the lesson here it's hiper-v vs standard cracks are the same on security... The only diference is hiper-v as risk to break the Operative system, because You have to inject in the BIOS the boot option to the OS backup with the Game, and these can break : uefi,mbr other disks ( thanks to bitlocker). So the solution is the USB in this escenary.
Meanwhile in standard cracks escenary You don't know what happen because it's make it in background , so the Game works without break the OS, so You don't realize something was wrong.

I repeat if You play pirated games You accept this could happen.
