@AudraTran Is it really removed from the web store? I'm just aware of removing Manifest 2 support (which is the old standard for chrome extensions) and just allowing Manifest 3 extensions. Because they removed some APIs in Manifest 3, which where used by ad blockers, they aren't working with Manifest 3 in the way they did with Manifest 2 APIs.
