Thank you for your help! It is important that you copy the app to the desktop, not just move it (the equivalent in a terminal being a 'cp -pr' instead of 'mv' command). If you drag the the application, it will just become moved, and then there is no issue. Another thing is that this does not happen all the time. It seems to depend on the state of the machine - the longer the machine has been running without rebooting, the greater the probability for encountering the problem.

Rebooting the computer helps, but only for a couple of hours. It would be nice to know why the machine gets into a state where the applications become blocked. Is there anything I could check, log files etc.?

Thank you very much! To reproduce the problem, the following is important: You need a machine with Apple Silicon and Monterey 12.6 (it's possible that the problem is there for 12.4 and 12.5 too) The app must be copied, not just moved (if you drag the app out of the build folder, it is moved, not copied) Could you please verify the above? Thanks again!
