Attempt to map database failed

This looks like a refresh of an old question. I'm using iOS 15 beta 7 and have presented a UIActivityViewController from a SwiftUI app. I get a ton of these errors when trying to share a two-item list containing String and UISimpleTextPrintFormatter.

[default] LaunchServices: store (null) or url (null) was nil: Error Domain=NSOSStatusErrorDomain Code=-54 "process may not map database" UserInfo={NSDebugDescription=process may not map database, _LSLine=264, _LSFunction=-[_LSDReadClient getServerStoreWithCompletionHandler:]}
[default] Attempt to map database failed: permission was denied. This attempt will not be retried.
[db] Failed to initialize client context with error Error Domain=NSOSStatusErrorDomain Code=-54 "process may not map database" UserInfo={NSDebugDescription=process may not map database, _LSLine=264, _LSFunction=-[_LSDReadClient getServerStoreWithCompletionHandler:]}
[default] -imageForImageDescriptor: can do IO please adopt -imageForDescriptor: for IO free drawing or -prepareImageForDescriptor: if IO is allowed. (This will become a fault soon.)

It looks as if the API is checking for entitlements I haven't requested, but I am not trying to share images. I just want to share text as plaintext or a nicely formatted printable attributed string.
