have you tried to a) increase exposure b) lay a print flat against the surface (like a test-u or something) c) releveling the bed after the swap?

@Trish I had tried increasing exposure and releveling. I tried printing flat against the surface and it worked! Does that just mean that I need to add more supports to what I'm printing? My supports already seem pretty dense, so I'd love to know of another way to prevent this from happening

I've also been having bad luck replicating it. When I changed files nothing worked again
