Why is my Apple Watch series 3 stuck frozen on the Apple logo

Hey there, neveah05.

There could be multiple reasons you're not able to use your Apple Watch, but we recommend trying to see if a force restart may help, as it may help get your Apple Watch get past this stuck state:

"Force restart your Apple Watch

You should force restart your Apple Watch as a last resort and only if it's not responding.

Don’t force restart your Apple Watch if you're updating watchOS. After you see the Apple logo and progress wheel, leave your watch alone and on its charger until the update finishes.

To force restart your Apple Watch, press and hold both the side button and Digital Crown for at least 10 seconds, then release both buttons when you see the Apple logo."

That information is from this article: Restart your Apple Watch - Apple Support If you're still unable to use your Apple Watch after a force restart, you can contact Apple Support for further assistance here: Contact Apple Support

Best wishes.
