I have a problem with launching MC on Magic launcher 1.3.4


New user
Hello, I have a non-premium account, I want to play on a mod-pack which was used by a Youtube artist. There are a lot of mods, so I am not gonna write all of them here. After I press play, launcher close, nothing happens except this, when I am trying to do this on PP5 cofiguration, I get a log

Can anyone help me fix that bug? I really want to play MC with this modpack.
