After updating, my saved passwords all disappeared and I can't save them again

Description of the issue:
After updating, my saved passwords all disappeared. Then, when I log into all my accounts again, the system did offer to save my details, but when I check in the autofill category, nothing there. I repeat it multiple times, but the same things happen. Really frustrating now and hope this can be fixed soon.

How can this issue be reproduced?

First time happened, I update 2-3 times before but it was fine.

**Expected result:
All my saved passwords return and I can save new passwords again, hope it will be autofill like before.
