My Apple Watch series 4 freezing every time , sometimes works perfectly for couple of hours I’m unpairing repairing every time hard reset can’t resolve this issue I tried with several iPhones & updated Watch os still same sometimes Digital Crown stopped working screen is always freezing how can I fix this

That sounds like a logic board issue, your best bet may be to try swapping in some parts but if that doesn’t work you might have to buy a new watch.

If you are still having issues, try this. Force restart the device (hold the crown and power button)Once the device turns off, let go of both buttons. When the apple logo appears, hold the power button (lower right one) until the erase all content option appearsFollow the prompts and allow the device to reset.Pair the device again Hope this helps!!
