Property DefaultLanguageName is not available Error on saving db settings When I open DB settings and try to change any setting it throws an error on save:


  Property DefaultLanguageName is not available for Database
  '[TMS-API555]'. This property may not exist for this object, or may
  not be retrievable due to insufficient access rights.
  (Microsoft.SqlServer.Smo)




It really does show empty language setting 



I tried to reset language via TSQL

EXEC sp_configure 'default language', 2 ;  
GO  
RECONFIGURE ;  
GO  



  Configuration option 'default language' changed from 3 to 2. Run the
  RECONFIGURE statement to install.


After that it still shows empty language and throws the error on save.

Tried

ALTER AUTHORIZATION ON DATABASE::dbname TO [sa];


didn't work

Facts:


I updated SQL Server 2016 to latest available version 13.0.4474.0
Windows Server 2016
Management Studio 14.0.17199.0
Logged in as sysadmin
If I create a new empty DB - there is no error and everything works
For a contained database, set the default language with ALTER DATABASE. For example: 

ALTER DATABASE [TMS-API555] SET DEFAULT_LANGUAGE = english;
