Unable to access hearthstone

Upon launching hearthstone I receive the “Playful sprites” error, the error in the top right reads: HS:NGRESULT DB ERROR:303:0

I have not been able to find a solution to this and previous encounters with this error make it seem like a database error on blizz’s side that I cannot solve myself. Can a dev please look into this issue? Thank you.

I’m having the exact same issue here! I hope there’s a reply soon because it looks like this isn’t the first time this has happened.
