Model 3 does not lock (connected with other effects)

For a few days I noticed that my M3P didn’t always lock cleanly. Today I had this many times (except for one exception, where it has locked correctly – with all the connected processes). I describe what happens (or not). I always use the iPone as a key, which has worked so well so far. With removal from the car the car locks, the mirrors fold in, the turn signals confirm briefly and the screen goes off. Now the car does not lock by removing n. If I then lock up via the app, it only locks, however, regardless of the distance (i.e. cell phone keys connected or not). The screen stays on and the mirrors don’t collapse. After quite a long time, the screen goes off, the mirrors stay outside. I tried a reset several times. Once it worked properly in between today, regardless of a reset, then no more. Does anyone know that? SW Version 2021.12.2 (since 7.4.21)
