[Question] There is a problem with the output of messages to the server console.

The first thing I thought about whas this post: https://github.com/sampctl/pawn-array-return-bug
Returning strings from functions can be problematic, at least when going deeper than a level.

However, I am not sure that is the issue here. Can you test another terminal (not using vscode embedded terminal)?
If that does not work, try to follow the thinking in the link above to test if it could be the case.
