SQL using mlstring and my import always crashes

Dear team,

I am connecting to SQL db. Connection works great. However, some tables are bilingual, there are mlstring in use, so due to connection to them I am always facing an error: 

"Microsoft SQL: An error occurred in the Microsoft .NET Framework while trying to load assembly id 65542. The server may be running out of resources, or the assembly may not be trusted with PERMISSION_SET = EXTERNAL_ACCESS or UNSAFE. Run the query again, or check documentation to see how to solve the assembly trust issues. For more information about this error:
System.IO.FileLoadException: Could not load file or assembly 'mlstring, Version=1.2.0.0, Culture=neutral, PublicKeyToken=****' or one of its dependencies. An error relating to security occurred. (Exception from HRESULT: 0x8013150A)

General error is:

Server team showed me request they are using due to SQL requests: 

"select top 3 Name.GetLangOrDefault('kz') from TableName;"

(- this one works for them in SQL).

Could you advice me what should I do to get data with PowerBI?
