Game Crashing in Raid

Hi there! So, I was attempting to do BWL last night, and as soon as my party engaged in combat, the game crashed. This happened a few times, but I just chalked it up to "it just happens sometimes." And then today, I brought my bots into MC and the same thing happened: we get teleported to the instance, but when we go to fight the first mob, it gets disconnected. I had been doing these raids without issue for the past few days. Any idea what could be causing this?

Thanks so much!

Edit: I tried again with a smaller group, and it happened again in DMN.

I've also been experiencing a bunch of disconnects today, but I am just running around Silvermoon city and questing.
