Plutonium

@Postal_dude1 optifine is a minecraft mod :")
i think the person is joking

so i keep getting this error when trying to start the launcher
ive seen several users having similar problems and ive tried everything that was recommended for them, but it keeps giving me the same issue over and over again.
ive been using plutonium since last year without any problems so i have no clue what the problem could be
and i have no idea what the error means either

it says the servers are fine as well btw
