Sounds like a potential virus scanner issue. Try to disable your virus scanner and see whether that helps. Some particularly invasive av programs can’t really be disabled unless being uninstalled unfortunately (e.g. BitDefender, Comodo).
If disabling helps, exclude the vorpX program folder (usually C:\Program Files (x86)\Animation Labs\vorpX) from scanning in your av program if possible.
If it is a virus scanner problem, please also report it as a false positive to your av vendor so they can fix it.
In general I would recommend Windows Defender, which finds a good balance between protection and invasiveness.
