I'm having a really weird problem with my Mac, and am wondering if anyone can help. I try to set the display sleep time (as it's currently set to 1 minute and that's way too short for my liking), but after I close system preferences, it totally resets to the previous value. Here's an Audio recording as well, in case this reveals something obvious I'm doing wrong. https://www.dropbox.com/s/sfonnc1od7ilv1b/20220314%200710%20Recording.flac?dl=1.
Any help is appreciated.
