Hi everyone, I have built programs for my personal use with Python. The logic is fine, but building a decent GUI is a hassle — most recently with Flet (Flutter), endlessly battling the framework. By chance, I discovered Objo a few weeks ago and gave it a try because it reminded me of the old days when programming was fun (Visual Basic). I was blown away. I could build something useful in hours, not in weeks or months! Of course, I bought a license.
Unfortunately, I now have a problem. I tried to make a build for use on my local machine, but a lengthy error message appears, and nothing further happens. I tried several times, and sometimes a message box announcing the build process appears for a second or so. The same error occurs with all projects, even with the included examples. I cannot copy the error to my clipboard, so I have attached a screenshot.

My machine is a MacBook Air M3 16MB with Tahoe 26.5.2.
Am I doing something wrong? Any help will be greatly appreciated.
