Hi @יהונתן דאיטי,
Thank you for your reaching out and welcome to Microsoft Q&A!
For the error message:
Could not obtain information about Windows NT group/user 'CS-ROBOTICS\yonatan.daiti', error code 0x54b. (Microsoft SQL Server, Error: 15404)
Please refer to the link in error message provided and verify the information below:
If this error is the result of a lack of a full trust relationship between the SQL Server service account and the domain of the Windows account, one of the following actions can resolve the error:
In addition, we can get the information from this official document:
Although any user with access to a database can create a diagram, once the diagram has been created, the only users who can see it are the diagram creator and any member of the db_owner role. If the diagram creator is part of a user group and not a member of the db_owner role then they require their own login to view the diagram.
Feel free to share your issue here if you have any concerns.
Best regards,
Lucy Chen
