Unable to continue Realm of light IV

I'm doing the Realm of Light IV Quest and died during the jump'n run section in the Elven kingdom.
Now the Quest NPC at the forest guardian is gone and i can't re-enter.
Is there any way to get back or is the quest just gone for me now?

 

If the "jump'n run" section is what I'm thinking about, you can return to that section through the portal under the giant fern leaves. Or if it is the library parkour, you can also return to that through the bell (I assume). If it's not these sections, what does your quest book say?

 

Already tried the bell, but the event doesnt trigger anymore. My quest book says to look for the plant inside the cave but I cant even get there cause Lari's portal is gone :/

 

The cave can be accessed without Lari, it's just a normal location on the map. Idk the exact coordinates, but it's south of the Forgery, next to a grind spot inside a valley, overlooked by the elven structures, namely the tower where you spoke with the Elder.

 

Ah okay, I thought that was a seperate location outside of the normal map since you got teleported over there.
Thank you for the help!
