I'm just posting this here since more people will probably have the same issue.

There was a guy in the help room today who had a problem with control groups 1, 2, and 3 not working. He figured out the problem himself while I was talking to him. It turned out he updated his nvidia driver and that caused it. Idk if there's a better solution than using an older driver but that's what worked for him.

Here's a link to the nvidia forum post he found on the issue:
