Same here.

after some testing, it appears that there is some funkyness going on in the interaction of leaves with lava. All the block(s) that caused the errors were leaves adjacent to lava.

Appears to be similar to #642 and others

@Kalmorph I tried Embeddium but it for some reason does not work/ doesn't show up and also does not recognize oculus as well for some reason

Same as #668 and #667

@GhostlyGaming @Apotrox and anyone with this issue, replace Rubidium for Embeddium for the time being, it works the same as Rubidium and doesn't crash about chunk meshes.

@GhostlyGaming I'm sorry for your issue as I have no knowledge on how to solve it either. It worked for me, so maybe you should check their own page, Discord or other places to know what's causing it.

@Kalmorph I managed to make it (embeddium) work, turns out it was an issue with one of the other mods but it works okayishh now, it still has some graphics issue when paired up with create, but I have managed to make it work for now

FYI, the issue i mentioned in my comment before (#642) had another comment with someone having built rubidium with a fix themselves. That works for me, doesnt have any rendering/graphics issues either. @Kalmorph @GhostlyGaming
