The file I'm working on just glitched out. In Eevee, we can see what it is supposed to look like, but as soon as I switch to Cycles, every material seemingly turns into an emission shader material. This happened before with another file, but in this one it affected every material and it happened randomly. Reassigning the material or a new material doesn't help. it simply turns into an emitter, even though the emission tab in the principled BSDF is completely black.
I have some more pictures:
1. Eevee rendered view, all lights in the scene visible

The only thing I changed between numbers 2 and 3 is changing from Eevee to Cycles (and hiding the other point light). Both are in the rendered viewport shading mode.
