Twisted Warden Revived Knockback Bug

Hi, I want to report a bug during the Twisted Warden Revived fight, the boss's knockback launched my character onto an out-of-bounds ledge where I can freely shoot the boss without it damaging me. Adding invisible barrier blocks to this boss area ledge will fix the exploit/issue. Please see the video I attached. It’s normal at first but during the fight I eventually get thrown onto a ledge and I accidentally fell back down.
