Internal connection fatal error connecting SQL Database

I am trying to connect to database using the PowerBI SQL Connector. The error message is: 'Internal connection fatal error. Error state: 15, Token : 16'

This error occurs when I try to connect to a specific database on SQL server. Other databases on the same server can be connected without any problem.

Thanks for the answer, I found that the problem is in the database collation, the error occurs when connecting to the database with the Georgian_Modern_Sort_CI_AS collation. I hope it gets fixed in the update
