I can reproduce this on a Catalina machine, working in R from the terminal.
This definitely looks similar to the problem that
rgl::setGraphicsDelay() was designed to solve, but even adding a 10
second delay doesn't help. I get a slightly different message than you:
> open3d()
error: xp_attach_gl_context returned: 2
*** caught segfault ***
address 0x18, cause 'memory not mapped'
but that might just be a different way of reporting the same underlying
issue.
It's clearly some kind of interaction between the Quartz device and rgl.
I'll see if I can track it down.

This is repeatable when the lines are all pasted in at once.
The example works if I allow some time delay between lines.
This is might be a relative of the one from a few months ago.
But this message is about invalid permissions.

MacBookAir with the M1 chip using the regular intel version of R from CRAN.
Big Sur 11.2.1.
The plot(1:10), col=7) ## went by default to the quartz() device.
I repeated this about 5 times in ESS, and then once in Terminal.
Let me know if you need more information.
