"Unable to retrieve information about the query" bug

Hi! I have been experiencing a bug while running new queries. I get a message that says "Unable to retrieve information about the query..." with error 404.

I think this has started since I turned on VSCode mode. But it may be not related to this.

I've looked into similar issues:

But they were all solved Retool-side and closed (there is no info on how to fix this client-side).

Anyone knows what's going on? Thanks!

Adding to this: "Preview" query seems to work, but "Run" doesn't.
