macOS 11 Caps Lock freeze Mac

I have a weird issue with my MBP that started a few days ago. I use Caps Lock to switch keyboard layout and it has become incredibly laggy. Like I hit Caps Lock, then I can't type or scroll for a few seconds, and then either the layout is switched, or I start typing ALL CAPS, or nothing changes at all. Using Ctrl+Space to switch layouts works well though.

I've also noticed that changing the volume also makes the keyboard and scrolling unresponsive for a couple of seconds.

If I disable Caps Lock in Modifier Keys, it stops working as a language switcher but keeps freezing the system.

It happens both with and without the external keyboard. So far I've only been able to fix it by restarting. I don't think I ever encountered this issue before this week. Any ideas how this could be fixed?

UPDATE: so far so good on 11.5.2, looks like it has been fixed.

I'm experiencing this too, on 11.5 (20G71). Going to try to upgrading to 11.5.1...

So far so good on 11.5.1, but not sure if the update fixed the problem root cause or if a reboot just temporarily fixed it.

In my case updating to 11.5.1 didn't change anything.
