iOS 13 upgrade on Xs max issue

iOS and iPadOS

Hello, I tried to update my iPhone XS Max to iOS13 but it seems to be stuck on the apple loading screen for 12+ hours. I tried to use some third party apps to try and pull it out of the loading screen but it didn’t work. It gets to the ‘swipe up to upgrade’ screen and gets stuck at the end of the loading bar. Is there any other way I can fix this without losing data? Thank you.
