UPDATE: This never really got solved, not by me and not by Apple, so I decided to go with a Class and update the view by adding a bool named "triggerViewUpdate" to my AppState class, and doing a "triggerViewUpdate.toggle()" whenever needed. This might not be the most elegant solution, but it works well enough for my use case.

That worked like a charm, OOPer, thank you!

Same here, can probably be ignored though which is hard for me because I hate warnings...

Just import SwiftUI in the file that needs @AppStorage support, no need to hold back on this convenient wrapper just because of older code, they can co-exist.

Responsible for this is ANECompilerService, have seen virtual RAM usage of over 407 GB right before crashing on an M1 Mac mini with 16gb of RAM. Crash pattern: slowing down opening a dialog to "Force Quit Applications" because I am running out of application memory (only Finder was running) freezing after a while, the pink/purple screen mentioned above + reboot
