I have been told stackhash crashes are 99% DEP (Data Execution Prevention) related.

I have disabled secure boot in my UEFI to be able to disable DEP using the command "bcdedit.exe /set {current} nx AlwaysOff" in the command prompt,

I verified after a reboot in the system settings, that DEP is entirely disabled, but I still get a
StackHash_2264 crash when I try to start the application. The application itself is a portable install that runs just fine on Win7 x64, I have most recent drivers yada yada yada ...

What would be the next step in diagnosing the issue?
