All other queries (MDX, DMX, XMLA) works fine, but DAX does not.

I have tried following to fix the issue:

Firstly I had tried re-install just SSMS.

When it did not work I have tried following steps still without success:

1. uninstall Visual Studio 2019 with SQL Server Data Tools (SSDT)
2. uninstall SSMS
3. install VS 2019 with SSDT
4. install SSMS

I tried to search for help on this issue, but I have not found any relevant information.

Thank you in advance for any suggestions.
