i've tested it and it works fine if i go through the default minecraft launcher. currently trying to load the pixelmon modpack in this error log, but it does it with my other modpack profiles too.
i managed to make it work by using an older optifine.
one step forward, two steps back, it crashed trying to generate a world.
