Can’t unpair apple watch

so my apple watch for some reason reset on its own and has gone back to the default welcome screen but when i open the watch app on my phone it still shows as paired. i then tried to unpair the watch but it is stuck on loading. when i press the info button it just says could not connect to apple watch. i have tried restarting both my phone and the watch but nothing has worked. i even removed the watch from my icloud account but it still won’t unpair on the app. what should i do?
