[2022] Wolf boss wont stop going underground.

i have an issue where the wolf boss (small fenrir) wont stop going underground. i run around for 4-6 min and it just spams that ability so i cant fight him. its pretty frustrating.
Any tips on how to avoid that ? i tried everything. shotting arrows, using abilities, following the wolf as close as posible while its underground to be as close as possible for when it emerges. nothing happens it just comes up for 1.5 seconds and jumps right down into its underground ability again.
and then sometimes if i get hit by the burrow im oneshotted other times it takes 2 hits.
