This does not work for me on iOS 16 - I get the same result where the Files modal immediately dismisses. Can you share more about your configuration, e.g. where you define ".myArchive" and the details in Info.plist?

This code doesn't work for me - it presents the Files browser and then immediately dismisses, just like my original issue. Can you share more info about your configuration - e.g. how you defined "myArchive" in Info.plist and the code where you extend UTType?
I'm seeing this same crash on macOS. @testinstadev did you find a solution?
