Dear PML88,
Thank you for posting your query in our community.
Based on your description, when you try to create a new project, an error will pop up.
To further narrow down the scope of the issue, could you please provide more information for me?
- If you go to the InPrivate window for a browser and log in with your account, can you create a new one?
- Do your colleagues have the same problem?
- Which Project license do you have?
- To check whether the problem is related to the tenant, we suggest that you contact your admin/IT admin to check whether your tenant has this incident in the Service Health Dashboard (SHD) via this link.
Thank you for your understanding and cooperation! Have a great day.
Sincerely,
Sean | Microsoft Community Moderator
