Has anyone Experienced this issue when trying to activate an Extension on teh local environment haven't seen anyhting wrong.

if its an older theme/extension it might not have been updated to use dart sass instead of jsass

Not the case, we already updated everything on the extension just made some chenges to styles from the live solution
