Problem with calls

I have these problems with Venu3 - (it only started now, at the beginning of the year - maybe a system update????)

- after ending a call to turn on my Spotify playlist :-) probably for the joy of ending a call??? :-D

- my handfree cars turn off - car call turns on, but I hear someone yelling into the phone "hello!" which is in my handbag.

- when the call starts, the sound breaks and the watch vibrates that a call is in progress - the call is dropped, I hear nothing for about 15s - I usually don't hear the caller's name and first words....

I've tried reset, turn off etc. It took a while to disable access to the phone microphone, but only for a while. Now I have everything disconnected from the phone... annoying

Any advice? Motorola (Android 13)
