Stuck in rol 2

I played the whole quest once, but after the fight cutscene and when i went back to the normal world, Lari were nowhere. When i track the quest it just says to "enter the taproot", I entered the taproot again but I come directly to the light forrest and doesn't progress in the quest. I think i've watched the fight cutscene like 4 times now but it still says "enter the taproot"
