"Invalid private key for encryption app. Please update your private key password in your personal settings to recover access to your encrypted files"

I have seen this topic from years ago but nothing recent when i searched for a solution. I just enabled end-to-end encryption, and i got this message.
NC Personal Security asks for the old log-in password and the current log-in password. Unless you manually type them in, you cannot click on the update private key password. I am able to do so but it says “saving” but it never becomes “saved”.

Note sure if you can see the picture but hopefully there is a simple solution.

I am facing he same problem, and looking for solution, too.

To whomever it helps: thanks.
