I doubt this is a lilypond problem.

I just installed 2.19.65 on my Windows 10 Pro system with plain vanilla Microsoft Defender and everything works just nicely. I therefor would (hesitantly) point my finger towards McAfee and/or your system.

You could try to uninstall/reinstall 2.19.65 and then disable McAfee and see if the problem persists. You may also file a bugreport/complaint with McAfee.

Kind regards,
Michael
