Application crashes on entering settings

[0gordonfreeman]

i customized my menu with some custom HA entities.
I deleted one of the entity in HA, because i sold it.

Since then the Settings of the Home Assistant Taskbar Menu Application can't be opened anymore.
The Application crashes with this error message:

Unbehandelte Ausnahme: System.NullReferenceException: Der Objektverweis wurde nicht auf eine Objektinstanz festgelegt.

I didn't know, that it's possible to sell HA entities 😃

You can remove deleted entity from config manually:

• Paste following address in File Explorer

  %APPDATA%\Home Assistant Taskbar Menu\Home Assistant Taskbar Menu

• Open config_view.dat file
• Remove entry for deleted entity

😆 🤣 that would be nice, but i sold one smart device...

i removed the whole json inside the file, now it's possible to access the settings.
thanks for your fast help

[PiotrMachowski]

Well, you didn't have to remove whole json, just one entry with removed entity would be enough

Fixed in v1.3.0.0
