Hello ! I'm so sorry for the trouble you're currently facing.
For this, there's no Official Solution towards your problem here. But, you can try to reset it to factory settings. It might help you with the problem. The community also search for the best Solutions possible, but for iPadOS 13.1.3 just recently release and many facing other problems (and, you are one of them).
You might want to try the Reset (who knows it will help to resolve your problem), here : Restore your iPhone, iPad, or iPod to factory settings - Apple Support
NOTE : Don't forget to do Backup first to prevent any Data Loss during the Process.
That's why i still use iPadOS 13.1.2, and didn't want to take any update for a while. (I took a note from community for Pros and Cons with iPadOS 13.1.3 and the result was devastating.)
