I recently updated my mac to Catalina (10.15.3) and I am using Xojo 2019.3… Previous projects are not launching, without notice.
I run the application, it then compiles and informs that it is launching the app, but after second or two it returns to the IDE without actually launching the app.
If I start a brand new web object it will launch properly.
I have removed all plugins (I only have MBS), and yet the same result.
This is also happen with the example projects that come with Xojo.
Please help me. I am stunned with this problem.
