Thank you for reporting the issue. I tried to reproduce the issue and encountered a similar kind of error message. However, after closing the error message window, I was presented with a new window titled 'Welcome to Document Intelligence Studio' that prompted me to provide some details. After providing the necessary details, the service opened successfully.
Therefore, I suggest that you try closing the error message window and reopening the service. If you encounter the same error message, please provide me with more details about the error message and any error codes that you may have received. I hope this helps, and please let me know if you have any further questions or concerns.
