Audio not recording smoothly/stuttering in Audition 2023

When recording in Audition 2023, there is a stutter/lag/delay. I thought it was a mic issue, as this happened yesterday while I was using my Yeti X usb mic. I swapped it out with another Blue Yeti usb mic, and the problem resolved. But today, it's happening w the second mic. I hit record, Audition captures less than 0.5 second of room noise, then it stops picking up any noise at all, and the record clock starts to stutter. Rather than running smoothly, the clock will pause on a time, then jump ahead. 0:00:491 - 0:00:497 - 0:00:591 - 0:00:631 - 0:00:664 and so on... It's not regular intervals, seems random. When I play back, it seems to have captured only the first quarter to half second only. It doesn't matter if I'm in a new file, in a previously saved file, using punch and roll or straight recording, multitrack or mono. It's capturing *some* of the room noise, so doesn't seem to be the mic. I've checked the settings and I have the correct hardware in and out selected. 

I just switched from Windows 10 to Windows 11. Could this be the issue? I've been trying to avoid going back to windows 10 given the time sink, but at this point I've spent an hour+ trying to fix this!

Anyone else have this issue? Advice re: a fix?
