I can confirm the the same issue occurs in vscode version 1.92 under both windows 11 and Fedora Linux 39. If the same .qmd file is renamed to .md file, hightlighting color is back to normal.

This same issue was reported to the vscode github project, and it is marked as "caused by extension".

A temporary solution is to downgrade to VS Code 1.91.1. I tested it on Windows 11, and it worked.
