Re: Console project deadlock

hi, hard to say without more details.  Start by enabling log with LOG_VERBOSE level then check logs once it happen again.

Re: Console project deadlock

Difficult to know what is wrong in your code.

Some ideas:
- First step is to move your startup code out of "Create" and put it into a dedicated method like "Run".
- Use a try..except and show any exception during this "Run" method call.
