First off, I've got Win11 for less than a month and there's no errors so right now I'm just assuming it's a Start11 problem as I don't have any lengthy experience with the product to know if this is common or not.

I've noticed that on occasion the clock will freeze. It's just the clock and everything else keeps on working. The only way to fix it is to go into start11 settings and restart explorer. From what I can tell it's just the clock that stops working.

MS did sneak in the 23H2 preview update on the 26th because it decided to turn back on preview updates somehow so I'm not sure if that is related.

The only thing I can say for sure is that it tends to stop working after playing and closing a full screen game, it's also not very consistent so this is going to be annoying to troubleshoot.

I'm kinda hoping someone here goes 'oh that's X'

Win 11 is v10.0.22631.3527

Nvidia 522.22 driver.

Start11 2.07
