This error is likely because of the style of paralleism that snowparam (as well as futures mutilsession) uses.

However, because we now decided this package will not directly be going on Bioconductor, its worth reverting the parallelism back to what it was originally. I do not think it will fix this bug but might as well check since its worth doing anyway, and then I can fix it from there.

@eboyer221 I can be the one that looks into this
