Thanks for reaching out.
Based on your message, it appears that you are utilizing a partner-based Open subscription, which has a specific capacity limit. Please attempt to create the lab again after a short while.
I recommend that you open a support ticket if you encounter any issues with the lab environment. Our backend support team will be able to assist and resolve your concerns.
Hello @Robert9 !
The partner based open subscription by design has limited capacity. Since it is already at capacity - I will suggest you to try after sometime.
You can reach out to the partner or raise a support case for any help.
