Game Center Achivement Not Working

so…I have unlinked and linked my Game Center ID, Reinstalled Apple Arcade’s Wonderbox several times and contacted Apple Support. I’m currently speaking with Aquiris Support and at the moment.

I don’t know if it’ll get resolved and this is my last resort, My achievement should’ve been unlocked after completing the Icy Matters Campaign, it was unlocked before until Wonderbox did an update.

If anyone has any ideas or other ways to resolve the issue, I’d highly appreciate it and thank you. :)
