Diablo 4 update

Is it just me, or since this last Diablo 4 update it’s no longer possible to play online?

I keep getting an error when I try to log in:

atualização Diablo 4

Is there a way to remove this update and put everything back the way it was before?

Before, everything was working fine. I didn’t change anything on my PC, my account is an original Battle.net account.

Help me with this error.
