would we encounter any problems with the game if antivirus removes/quarantines the crypticerror.exe file?

sonar did that, so just wondering if i should restore it or reinstall or what :p

Sonar is falsing on this, known issue and is sonars problem of course.

You need to replace that file as its needed for error reporting.

Defacto response is always going to be "disable your antivirus while gaming"
