Hello, one day I have this problem, when I enter with the pvp mods package called labymod I get a mistake. THE GAME HAS CEASED TO WORK. AN UNEXPECTED ERROR HAS BEEN PRODUCED AND THE GAME HAS CEASED TO WORK. only when I enter with the Pvp mods pack helps

When I enter my .minecraft folder and enter the crash reports folder I get this, help please I want to practice pvp, only this appears when I use the pvp mod later when I play it without mods I do not skip any errors
