I am using FW 1.6.0 on my EOS R. I just received my Rokinon 14mm AF Canon EF mount lens. When I use manual focus, it delays, fires the shutter, then freezes up for about 40 seconds. Ultimately the photo is taken, but this is not how it should act. I have release shutter without a lens enabled. When I attach this lens to a t5 or t3i, it works absolutely fine in MF mode. Any thoughts as to what I am missing?

Again. Exactly which model lens are you using?

It seems that you may have an old lens that works with old cameras, but not a relatively new camera. Sorry, but that is a lens problem. Old lens does not work with more recent camera body.

BTW, you might not need to enable releasing the shutter without a lens. It should not make a difference, though.

The “Rokinon 14mm AF” Lens does not use a Dandelion AE chip. It is an autofocusing lens, not a manual lens with a focus confirmation chip.
