I faced the same problem when I upgraded Studio Pro to 8.18.23 from 7.23.13, but was able to resolve it myself.
Try opening Database Properties (Options Page) in SQL Server Management Studio and check the Compatibility level.
If this value is older than SQL Server 2019, Mendix will recognize it as an older version of SQL Server and give you an error.
Changing this value to SQL Server 2019 worked for me.
