I could not compile any class. I've fixed this I removed all IPM and SourceControl classes via management portal, then set SourceControl to nove in my namespace and rebooted IRIS. After reboot I was able to reinstall again IPM and Source Control.

Problem was that VS Code does not provide any error. I was getting only 

Executing Studii Action "Opened Document" on IP:PORT failed. Check the ObjectScript Output channel for details.

After I installed Studio I saw problem directly. 

I figure out with uggly code in html 

#($ZCONVERT($$$Text("My Account","webshop","sk"), "O", "UTF8"))#
