Cant Download Any game

Im trying to download wow for days, and i tryied every single thing you can think to resolve this bug, i wiped all battle net archives from my pc, reinstaled it, disabled windows defender, used vpn, etc.

Nothing changed, except the error code after the loop of inicializating download.

Got an huge list of errors from Battle Net Agent all with the same error
Failed to read db info from ‘C:/ProgramData/Battle.net/Agent/product.db.new’

and next to it : Invalid metadata hash given (Insert random characters here)

TBH this is the worse launcher i ever used, im surprised how effort they put to make this so bad.
