BTT Crash after creating a Stream Deck button with custom icon

Bug Reports
1

I was creating a new Stream Deck button then i've selected a custom icon from my disk.

BTT crashed.

I can restart the app, everything works fine but when i click the mentioned button crashes again.

The biggest problem is i cannot select the "broken" button to delete.

So, i wonder if there is any way to delete a button without selecting him?

Here is the debug log:

Note: I was able to delete the button by selecting another one and delete both at the same time.
