After the long break I currently back to Salesforce ecosystem and I'm trying to setup my development environment - Visual Studio Code with DX features (Salesforce CLI, Scratch Orgs etc.) and Windows Subsystem Linux (WSL2). I installed and configured everything as supposed to be in Salesforce Docs but code completion not working in my VS Code. Without using WSL2 everything work as expected.
I had run out my ideas. It would be great if I will be able to take advantage of all Salesforce Extention Pack features.
Update. I noticed that Apex Language Server won't start.
