Watch screen goes randomly black and watch is perfectly working underneath. The only way to reactivate screen is b taking watch off and then afterwards screen works again.

Did you already try to erase the watch and pair it again, setting up as a new device instead of using the latest backup?
Unpair and erase your Apple Watch - Apple Support
Before you do that, try force restarting the watch, in case it is just a glitch.
To force restart your watch, press and hold the Digital Crown and the Side button together for about 10sec, until the Apple logo comes back again.
