Since I changed to a Mac M1 (16") I have this problem with BTT.
1 or 2 times a day or more, it freezes launchpad, mission control and I don't access other desktops.
I can only fix it by resetting the "dock" from the activity monitor
I have the latest version of MacOS and I only have the Aerial app installed.
With my previous mac (i9) it didn't happen to me and if I don't run BTT it doesn't happen.
Thanks
