SOLVED - IOC works on B0 but not B5

[Demon]

I don't understand how you seem to have disabled the PPS for pins B0 and B5 without allocating something to them. Don't they need something allocated to them whether it's a port access or peripheral whatever if you plan to use the pins?

Apologies, I'm still learning this stuff,

Yeah, so am I.

I looked for a way to move "treat this like a GP pin" via PPS settings, but I don't see anything like that.

Unless you just can't recycle CCP pins, unless you move another peripheral to it (which is very possible).
