Rider suddenly can't find info.plist file

Rider has started failing to run or debug my app, with the message “Error running 'MyApp.iOS' Info.plist not found”. The info.plist file is right where it has always been, in the project directory generated by a script. Rider even shows in in the solution sidebar.

I updated to macOS 15.0 yesterday, so I suspect that may be related. I'm using Rider 2024.3.2. I have tried restarting the app, restarting my computer, git clean, and invalidating caches.

Is there something about macOS 15 that affects where Rider looks for files? Is there some other cache I can reset? The error message doesn't seem to come from a log, so is there a way I can find out where Rider is looking?
