Garmin 8 fenix stuck on map updates showing 100%

Hi,

I started install Europe Topo Maps on Garmin, and now I can see only this screen on my watches:

Garmin 8 error

If link doesn't work, screen is from updating maps it is showing 100%, but watches are totally locked. Garmin Express show that "You are up to date", but after I click on sync button I get error "There was an error syncing with Garmin Connect" I tried hard reset, but it didn't help.

Could you please help me what else I can try ?

Thanks MK
