Debug failure for invalid type alias statement

[dhruvmanila]

Describe the bug

It seems like the server is failing to possibly log the syntax error for the following code:

type def = 1

Here, def is a keyword but is not allowed in that position, only soft keywords are allowed there.

Code or Screenshots

The code is mentioned above. The error traceback is:

VS Code extension or command-line

I've tried it using both and I'm getting the same error on both:

• Pyright version (via the CLI): pyright 1.1.363
• Pylance version (via VS Code): v2024.5.1

This is addressed in pyright 1.1.364.
