Program Monitor Doesn't Play Footage

[dorb]

Here's all what I did, which is pretty standard workflow over here:

Resized the sequence to fit short form content standards, scene edit detection on the larger edit to find the cuts, send to After Effects to track the faces, send the sequence back to Premiere, and then transcribe the captions.  Now the program monitor won't play the edit, even though I can still scrub through them just fine.  When I push play, it just sits there.

This was not happening prior to the recent update.

Looks like it also won't play in the source monitor either.  Same story, I can scrub the timeline but no audio.  I tried to export and the file also had no audio, but worked otherwise.  No idea what's happening.

Okay, so I restarted my computer and problem fixed I guess?  Idk, everything works fine now.
