Fatal error: Duplicate keys of type 'DisplayList' were found in a Dictionary. This usually means either that the type violates Hashable's requirements, or that members of such a dictionary were mutated after insertion.

this in a WXPython 4.02 app (wx not upgraded recently) and wx doesn't have a 'DisplayList' class and neither does my app.

started happening shortly after upgrading Wing Pro, but I also upgraded the OS too

this isn't an exception. it gets written to the Debug/IO window and debugging stops OSX Sonoma 14.3.1 (23D60), WING Pro 10.0.1.3 (rev 363662fe5c92)

seems like this is a swift related thing so may not be in wing see: https://forums.developer.apple.com/forums/thread/726582
