Macbook bug after 11.5 and 11.5.1 update

I have a 4 month old Macbook pro m1 which started to have 2 bugs after I update it to 11.5 update. when I press the caps lock key it lags my mac for like a second the mouse pointer the screen and even audio if I have a music playing I know this is not a hardware issue because when I restart my mac the caps lock works just fine for some time and only starts lagging after a couple hour of use and I have cleaned my keyboard in case its caused by dust. The second bug is that screenshot takes a second to happen it used to be almost instantaneous but now it take 1-2 second to happen. These started after 11.5 macOS Big Sur update. apple then released 11.5.1 update which i thought would fix it but it didn't. Is anyone else experiencing this? Is there a way to fix it?
