Fenix 7 became useless. Freezing after doing anything

Hi,

Yesterday I traveled from Europe to Costa Rica and would it be possible that the timezone change *** up my watch?

I'm on software 16.22 and made sure I did all the updates before I left.

Now it keeps freezing after a minute or so or if I scroll through the watch. Every time.

I then hold the light button for several seconds and start back up again.

It's completely useless this way. I'm very frustrated because I bought the watch for these trips.

Anything I can do? Anyone tips?

If I try a factory reset, do I lose al the downloaded maps? 

Thanks in advance.

Wouldn't want another watch, always been very happy with it, but this is unacceptable.

Thijs
