@ggyorfi Thanks for your feedback!

May I have the following info for investigation:

1. What's your OS?
2. What's the version of your VSCode?
3. What's the code snippet causing the problem?

Hi @ggyorfi,

I'll close this issue since it's outdated.
Please check out the latest release v4.1.1 and feel free to re-open it if you ever encounter the issue again.
Thanks!
