I have exactly the same problem. I can't debug the program at all. The whole thing gets stuck. There is a CrossThread error in the Windows event log! I debugged your program using x32dbg. And among other things, you have an error in SetThreadName , Unknown name. this error causes the program to hang often. Unfortunately, it still says Executing... and I wait an infinite time, I have to kill the process. We have purchased this program and I need it to work. I tried all versions from 12 -> 15. Unfortunately, I have Windows 11. And it happened after the last update, the update is KB5021234, I tried to uninstall the update but the problem was not solved. I think the problem is with you and you will have to make better compatibility.If you want contact me at email@example.com. I'll give you a crash dump, logs, whatever.
