Hello maladl,

I have a few questions for you that will help narrow down what issue it is that you are experiencing.

Quick questions:

Does this happen for every project?
Could you try verifying your engine (example below)
Does this happen for clean projects?
Could you provide your complete callstack (including login ID)?

Example (verify engine):

Hello Rudy,
The engine doesn’t start at all and i don’t even prompt the choice of project creation so yes it happens all the time.
