LSOpenURLsWithRole() failed with error 10810

[Centre de Formation France]

Hi,

I compile my python 3.8 program in Mac OS X Catalina.

When I double click on MyApp.app, I see its icon opening but then closing.

SO I tried to open it from terminal to get some log info:

sudo open MyApp.app

and I get this error message:

LSOpenURLsWithRole() failed with error -10810 for the file /Users/GB/Python/MyApp/dist/MyApp.app.

I made some search on Google and I saw I was not the only one who had this issue. Unfortunately, no solution was found.

Can anyone help me please?

Hi,

This could be a code signing issue. Apple seemed to have tightened things up
recently.

Check the system log for additional info.
