You could long tap on SD Maid SE, tap on the “!” or “app info” or whatever it’s called on your system, tap “permissions” and enable the necessary permissions there.
I installed mine a long time ago so I’m not sure, but doesn’t SD Maid SE need a rooted system, or superuser privileges somehow? My Magisk app (which grants these privileges in my case) has SD Maid SE registered as such.
I uninstalled it. I’m going to install it again and give it access.
