How to make Remmina save password?

Question

linux

Attention! Slippers to rush!)) I
installed Remmina on Linux Mint 20.3 and at the end of the installation I automatically clicked "ok" (cancel in Windows at this point).
Now it has been updated to 1.4.23 and it refuses to save the password from the session both when editing and when directly entering the "remember password" slider does not respond. The rest of the users have 1.4.2 and everything works fine.
I read that you can do a downgrade, but for me it's still difficult.
When reinstalling the program, 1.4.23 is installed immediately and the session created before deletion immediately appears in the list.
Maybe parts of the program remain after removal? (for example, a session, it pulled itself up from somewhere)
How to clean up the program after uninstalling it completely? (maybe after that, during installation, the manager will again throw out the update window and I will press the correct button)
How to roll back an already installed program to a previous version?

How do you remove a package? remove or purge? the remove command does not remove the configs
remove the package - sudo apt purge package-name (maybe it will be necessary to delete its folder if it doesn’t do it by itself)
