Temple Architect infinitely forking projectile - urgent

Video demo https://www.youtube.com/shorts/oKGEwLFhKeI - not mine, but it happened identically - Architect casts initially 9 projectiles (from +2 extra projectiles added to temple mod pool from medallion that adds mod from waystone mod pool), which seems to cause projectiles infinitely forking, filling whole area, instantly killing character, bringing framerate to single digit, VFX not being loaded properly and still forking even after death of character. Needs really fast fix because at this rate I can't run Architect room without dying. Both video's owner and mine temple had common part - +2 projectiles extra mod.
