My friend cant follow me into large worlds (bigger than 40-50mb)

heres the facts:

she always freezes or gets kicked to her home when trying to load a world. this will happen at random. sometimes at 3% loading sometimes at 50% etc. theres no pattern except that she mostly doesnt get it for small worlds.

-shes on quest linked to her PC
-she tried both airlink and cable connection
-she tried it on the desktop version aswell and the issue persists even in desktop mode
-she tried deleting her prefferences and reinstalling VRC
-she cleared avatar cache and world cache

nothing works
