[macOS Sequoia] Sudden surge of "failed to retrieve app-scope key" logs and failed URL security scoping

Hello,

with macOS Sequoia I've observed a sudden, substantial surge in reports about the Mac App Store version of my app Yoink no longer accepting files dropped to it, with the following message being logged in Console.app:

08:16:05.516307+0200	Yoink	---Yoink Error--- Could not create NSURL bookmark for /Users/<redacted>/Downloads/<redacted>/<redacted>.txt
err: Error Domain=NSCocoaErrorDomain Code=256 "Failed to retrieve app-scope key" UserInfo={NSDebugDescription=Failed to retrieve app-scope key}

The code line that causes this is the following:

NSData *bmData = [fileURL bookmarkDataWithOptions:NSURLBookmarkCreationWithSecurityScope
							   includingResourceValuesForKeys:nil
												relativeToURL:nil
														error:&err];

Sometimes a relaunch of Yoink, or a restart of the Mac resolves the issue, but only temporarily. Other times, even a restart doesn't work, but running

tccutil reset All at.EternalStorms.Yoink

in Terminal and then restarting the Mac works (again, temporarily).

The trial version and Setapp versions of my app both work as expected, however.

I myself cannot reproduce this issue, so any pointers would be greatly appreciated.

(This might be considered a follow up to https://developer.apple.com/forums/thread/46583 , years back)

Thanks a ton,
