Cannot create app after adding arguments

[jsantos42]

Whenever you add an argument for the script, you can no longer get 'Select Script' and 'Create App' buttons to work.
I'm on Mac OS 11.6.

Experience the same on Mac OS 11.7.1. It beeps at asking to "select destination", but no windows appears to do so.

Same as above with MacOS 12.6. Behavior remains the same even after you remove the shell argument.
Viable workaround -- create the profile in GUI but use CLI command to create the app with the desired additional arguments.

Same issue with a couple of screenshots (didn't find this already existing in search)
#241

Same issue on Ventura 13.1 (22C65). It seems like file picker stops working in general - same behaviour when trying to change icon via Select Image/.icns File...

I've discovered the source of the bug and will release a fix soon.

Is there a fix for this yet?

[edit: discovered a workaround, if you run platypus its from the command line just with open /Applications/Platypus.app/Contents/MacOS/Platypus it works as expected thereafter.

I'm having this problem as well. Starting it from the command line doesn't help.

[sveinbjornt]

This is a known problem (due to changes in AppKit modal dialog/sheet handling in macOS) and will be fixed in the next release, which should arrive soon. In the meantime, the workaround is to use the command line tool, or manually edit the AppSettings.plist file in the generated app, or go back to Platypus 5.3 (which has no ARM64 support).

Starting the GUI app from the command line shouldn't make any difference.
