Lineage OS 14.1 ROM can't connect to camera

Answering my own question.

My particular problem had to do with baseband and device codename, no bugs or problems with the build. For those, like me who were unaware of how this is related.

My baseband version matched the fortunave3g codename. So I should have installed that build of the of the ROM instead of fortuna3g, like I initially had. More information can be found in the device model master thread at xda-dev forums

I was unaware of the relation between the two things. But anticipating issues I had previously downloaded the three available builds (fortuna3g, fortunafz & fortunave3g). So all I needed to to was flash the appropriate build.
Everything is working fine now.

Thanks to all for the attention. Ultimately my problem was lack of awareness.
