Lithium as well, if I recall correctly. Most lithium is theorized to date to the big bang. There are no current pathways to create it, and only pathways that destroy it.
Most helium also dates to big bang, but some was created through fusion or alpha decay.
Forgive my uneducated arse but is this a problem that cold fusion could solve? Like, could we theoretically create stable isotopes to use in significant enough quantities by fusing atomic nuclei and chucking in or subtracting some electrons from the mix?

No. A lack of stellar pathways to create lithium means that there isn’t a fusion chain that includes it. Recent evidence points to it being produced by particle bombardment in classical novae though, which we could in theory reproduce in particle accelerators. It would be ridiculously expensive though.
