Hi Shinde Sudeep,
Are you trying to create in developer portal or in Mendix studio pro?
Could you please share error of the warning message here?
I believe I have the same problem in the Developer app. Below the message I’m getting:
We were not able to create a project at this time, but click "Try again" to give us another chance. If it doesn't work, please check the current status of the developer portal or let our support team know and we'll get right on it. Sorry for the inconvenience!
The same message since early this afternoon :-(
