On my vscode extension(https://github.com/razetime/bqn-vscode) I am getting an error which doesn't quite stem from my code:

(node:7292) [DEP0005] DeprecationWarning: Buffer() is deprecated due to security and usability issues. Please use the Buffer.alloc(), Buffer.allocUnsafe(), or Buffer.from() methods instead.
(Use `Code --trace-deprecation ...` to show where the warning was created)

The path of the file is C:\Users\<username>\AppData\Local\Programs\Microsoft VS Code\resources\app\out\bootstrap-fork.js, and I don't understand why it is causing this issue.

As a result, the extension is not running, and the main requirement of it - backslash symbol completion is not working. How that works is typing backlash and then a different key to get a required symbol. I'd like to know how to solve this, so I can get that working properly. As of now, it errors with command 'language-bqn.backslash' not found
