Pillager attacked me in Creative mode 1.20.6

I was playing hardcore and decided to turn on cheats. I went to LAN, turned on cheats and set my gamemode to creative. I found a pillager outpost. I fooled around, switching between creative and survival. But then, when I switched to Creative again, a pillager started attacking me. Of course, I was in creative mode, so no damage. I think it might have been because it started loading its crossbow when I was in Survival but then I probably switched to Creative before it finished loading. Here's the seed in case it has anything to do with this bug:
