Hi
This is a bit of sticky situation isn’t it!
At the moment I think the best thing you can do is plug it in to a Mac and use finder to try and make a backup but if it doesn’t let you do that your only option may be to restore it
Here’s some videos on making backups and restoring

If you are on a windows computer you will need to follow along with these videos(linked below)

If all this doesn’t work please let me know and we can try something else
Hopefully this helps
Any questions please ask
Thanks:-)
