64 Bit game doesnt run while 32bit does

Hi when im testing in the ide everything works fine. so i started compiling for windows using YYC compiler.
the 32bit compiled
the 64bit compiled

when starting the 32bit the game works as expected.
when starting the 64bit version it doesnt even start just nothing happens?

I tried clearing cache.
Reinstalling the IDE
Reinstalling visual studio and its packages.
Everything is up2date.
No errors during compile.

Anyone any idea where i need to search for this issue?
Thanks in advance
