Decryption error

Hello,
Thank you so much for this great app, I use it daily.

The problem is I couldn't manage to decrypt my notes after changing my operating system.

My android phone got broken then I started to use a flip phone. After that I installed linux mint 20 on my windows 8.1 laptop without exporting my data. (how smart)

I've installed Joplin Appimage version 1.1.4. Synced via dropbox but all notes are encrypted. On encryption section there is an active master key. But my password didn''t work.

Then have also installed android app version 1.2.2.2097578. Same thing happened.

The problem looks like my password. But I saved it to password manager, it can't be wrong.

Is there anything I can do? Please help.
