Additional information

First reported by Dj on Discord.

As suggested, removing the desktop_app setting fixed this: everything rendered correctly with no warnings.

Appears to be the same root cause as #11235.

Ran this on my Linux machine originally. Compiled, no errors, but no window spawns.

However, during the writing of this comment, I left the program running in the background, and it did EVENTUALLY open. I tested this to take around 61s +/- 1s across 3 attempts to spawn the window compared to nearly instant when .insert_resource(WinitSettings::desktop_app()) is removed.
