I have this problem.
Have you solved it?

@iwctwbai, the solutions related to Tkinter and Tcl in pyinstaller/pyinstaller#3820 didn't related to my particular project, so those fixes didn't work. I may give a try to using a bundling application like Playtpus, also suggested in the original thread.

This was not an observed issue in previous releases of this project, so I'm hypothesizing it does have something to do with the MacOS version. Will post my solution when I have it.
