My password manager won't save my passwords

I’ve been using the Avast browser for years and I haven’t had any problems. They save just fine. But for the last month or so I’ve had issues with my password list disappearing. I’d add them to the list, but then if I close the tab and go back to it, all the passwords are gone. I tried looking up the issue on the forums, but either I wasn’t looking for the correct topic or no one else has had this issue. Some things that may have effected the problem are several Windows updates, including yesterday when it looked like I had lost everything I had installed on my computer. The desktop screen was different, icons for apps were missing I looked for my pictures and there was nothing in the file. I freaked! Then a friend found something on a Windows forum that helped restore my preferences, desktop, app icons, etc. The only thing that didn’t restore was my password list. Only thing I can think of is to type all the passwords again and see if I can export it to a .csv file and save them all before I close the tab. I’m lucky I have a lot of the same apps and logins on my phone. I’d memorize them all, but my brain doesn’t work like that (ADHD brain), and many sites want passwords way longer with extra numbers and symbols to make them more secure.
Thanks in advance.
