The game does not recognize the resource pack version

?
It’s not a bug, but in the Datapack version 82, pack.mcmeta changed, look at the 1st change log of the 1.21.9 snapshot

Resource packs supporting formats 65 and up must declare a min_format and a max_format in their pack.mcmeta file. Adding the new formats to the range specified by the old supported_formats field is not enough. This is not a bug.
