Something in your system is probably messing with ArchiCAD.
Can you turn off antivirus and see what happens?
Also, please state your computer specs.
What I am specifically interested in is what brand it is and what kind of preinstalled accessory program are there in the system.
In one of my older machines there was a data protection program preinstalled and it did not let ArchiCAD access its own folders in the Program Files folder so AC just quit whenever I started it.
After I uninstalled that (unnecessary) program, everything went back to normal.
