SMBXb5 crashing after starting an episode

[Jeng1man]

I recently installed SMBXb5 to play the SMARTS Demo, but whenever I try to play the demo or one of the pre-installed episodes, the launcher closes, and I hear the Windows error sound.
I tried installing the b4 version, which works completely fine, but SMARTS is only playable on the b5 version. I suspect the issue is related to LunaLoader because I'm unable to open the b5 version of it at all.
Does anyone know of a possible fix?

I was able to solve the problem.
The Anti-Virus Program F-Secure stopped the new Version of LunaLoader from opening.
For whatever reason.
