^{Originally posted by KedneckInc September 8, 2023} Environment:

• Windows: 11.?
• Visual Studio Code: 1.82.0

What has been tried:

• Latest PreRelease,
• Latest Released,
• Released Version 0.20.0.

The crazy thing is it was working just a day or three ago! I’m afraid I didn’t note which version it was running at that time.

The attempt to start the language server gives results like this. This sample is from 0.20.0:
