I bought the MX Master 3S for my MacBook Pro with M2 Max chip. At first I had no problems with the mouse, but after a day of active use, the mouse started to block or affect my integrated laptop keyboard. Instead of typing letters, the keyboard behaved as if I was constantly holding down the option key (G became @ without using shortcuts or 8 became { etc.). As soon as I switched off the mouse, the keyboard of the MacBook worked again as usual. When I checked the settings, I saw that LogiOptions+ requires access rights to the keyboard input, otherwise no individual button programming is possible.
Is this problem already known or is there a solution?

Hello doriiian

It's been working fine for me since I bought it. I use it on a MBP 15' (2019). Maybe you can uninstall the Logitech app (where you can personalise it) and reinstall it. 
I can't think of anything else.

Many greetings

Hello, the Logitech works fine for me. Check in the system settings whether all access rights are enabled. Otherwise, I would install the latest updates and reconfigure the Logitech.
Out of curiosity, does your Mac behave the same way with the display closed or open?
