FireFox saved logins on PC corrupt after Windows Update

After a Windows or FireFox update (both had occurred before I realized there was an issue), my saved logins on my PC is corrupt. All of my saved logins on my Android device are intact. I have tried to restore previous versions of the file as well as the key3.db but there are no previous versions. The only other login jsons file is the new one created by FireFox when the other was determined to be corrupt. I have tried a system restore and it also failed. Is there a way to locate the file on my Android and copy it and replace the corrupt file on my pc. I've searched the forums to the best of my ability but have not found a suitable solution.

key3.db and logins.json : These are the Password files. Copy Both !

In the event that the passwords information is lost, you should record all information in a separate text file somewhere else on your hard drive, or written down. You can easily copy and paste if you need to do so. If you are concerned about someone else looking at that file, you can compress it using a password.

Can you check the logins.json file in a text editor to see in what way the file is corrupted?

If there are only null bytes in the file then nothing can be done. If there is still text in the file then there might be a problem with key3.db.
