App crashes trying to save dial switch settings

It took me A LOT OF ATTEMPTS to setup the dial switch using the app in the first place, but now, it DOESN’T SHOW the current setup (it is working), therefore, i tried to setup again the buttons I wanted to change, but the app crashed upon trying to save. So I tried to reset all buttons, that also failed with a crash

Please follow Crash when configuring switch - #9 by Thomas for updates on this issue. If anyone can provide the information in the linked post that would be helpful.
