Description:
I found a crash on the 1.17-7 update and older with starting rituals using a dispenser w/ athame method. It doesn't matter if there's items, or if it's a valid ritual, or if you have enough altar power. It just crashes no matter what when trying to activate a ritual that way. I have only done this with the player in the area and in the overworld dimension. The ritual also doesn't actually start if you join the world after the crash. This also triggered a crash on a server, but only crashed the host & not the client. I am using a variety of mods, which the list is in the crash report if the issue is a mod conflict. I'm also using the "Not Enough Crashes" mod to provide more details on the crash.

Reproducing the crash (The steps I took specifically):

1. Create an altar with or without sufficient power. (May or may not be necessary to have an altar. Untested)
2. Place a ritual circle of refining. (I only tested it with this ritual)
3. Place a dispenser w/ athame inside, 1 block away from the gold chalk, facing the gold chalk. (No blocks in-between the dispenser & chalk.)
4. Activate the dispenser with a stone button. (How I activated it.)
