Anim notify causing crashes in multiplayer

Hi, This issue only started today, and I haven’t touched anything to do with the code surrounding it in weeks, so it came out of seemingly nowhere. I have two anim notifies (light attack and heavy attack) that fire to start calculation damage for the wielder’s weapon via a line trace on the weapons blade. Up until now I’ve never had an issue, as stated above, but today it spontaneously started causing crashes when either of these notifies had event nodes in an animation blueprint. The most bizarre part is that it only happens when the game is run with more than one player. In single player everything works exactly as intended and as it always has. This isn’t my first time testing these in multiplayer so the sudden crashes are really perplexing. If i take the events out of the animation BP it no longer crashes, but even if they are in there completely unconnected they still cause crashes when fired. Can anyone help me?
