App crashes everytime after failing to import an autobackup. "Parameter specified as non-null is null" and "cursor.getString(1) must not be null"

Question

App crashes everytime after failing to import an autobackup. "Parameter specified as non-null is null" and "cursor.getString(1) must not be null"

Describe the bug
The app crashes after trying to restore a backup. After the initial crash, the app will crash everytime you try to open it. This issue exists both in stable and beta versions. I believe this is the same issue from #854, which was left unresolved because the original reporter bailed.

To Reproduce
Steps to reproduce the behavior:

Install the latest beta
Open the Handy Reading app
Allow access to file and media
On the "Do you want to import feeds and app settings from autobackup file" dialog, tap "Ok"
Select the backup file
Wait
The crash happens

Expected behavior
I expected to be able to import an existing backup without the app crashing.

Screenshots
I've recorded a video of this issue: https://www.youtube.com/watch?v=9nF0x_5LimQ
Here is the backup file I tried to import: https://mega.nz/file/EpgGBSJS#vBSh8vmWVnHWoh22UXPazNMaX39y7XW6lScAPGojN0s

Smartphone (please complete the following information):

Device: Moto e6 plus
OS: Android 12
Browser: Firefox
Version: Handy Reading v0.19.10

Additional context

When the app first crashes, this is the error it throws:
