Drusian the Artillerist Rogue Exile crashes game and eats entire waystone

Met him three times and he's crashed me the last two times

If it helps, here's some details
-Happened on Steaming Spring and Abyss.
-On Abyss, map was completed and cleared but after he crashed the game it was turned into map attempted.
-First time, when I didn't crash he wasn't wearing anything uniques. Could be a coincidence.
-I'm using a thorns build, unsure if it crashes when he hits me or when the barbs proc, or when he dies.

EDIT: it doesn't crash the game, it sends you back to the login screen. Needed to clarify.

Can verify this bug report ref no. 2497593889, lost 4 maps including a citadel and nexus because of this rogue exile, kicks you to login screen and crashes the map instance. This one is too bad cause the map counts as failed. Please help GGG. For more context I'm also playing a thorns barbs and quillburst build.
