In previous versions of Ubuntu, you could right-click a desktop shortcut and select "Don't Allow Launching" to convert the shortcut into a text file (i.e. you could double-click on it and it would open in your default text editor).
In 22.04 LTS, the "Don't Allow Launching" option simply breaks the shortcut - the icon itself turns into a broken state, and double-clicking it triggers the same "not trusted" errors that others have reported.
Admittedly, the "Open With Other Application" option is quicker than the conversion, but this change seems like a regression. Is there a way of restoring the old functionality?
