The backend version is not supported to design database diagrams or tables
This is commonly reported as an error due to using the wrong version of SSMS(Sql Server Management Studio). Use the version designed for your database version. You can use the command select @@version to check which version of sql server you are actually using. This version is reported in a way that is easier to interpret than that shown in the Help About in SSMS.
Using a newer version of SSMS than your database is generally error-free, i.e. backward compatible.
Microsoft SQL Server Management Studio (2012)
The error is literally telling you the problem here, the version of SSMS you are using (SSMS 2012) does not support the back end version that you are using (SQL Server 2019). I can tell it's 2019 because in the top left of that image it has Version 15......
The first version of SSMS to provide support for SQL Server 2019 was SSMS 18.0, which was release on 2019-04-19.

Database Design and relation diagrams details
I think your solution is to use a database diagram (https://msdn.microsoft.com/en-us/library/ms189078.aspx)
Just drag all tables on the screen and it will show you the relations, this of course only when the primary-keys/foreign-keys are there.
