So It appears that X11, a.k.a. XQuartz on a Mac, is failing to load. You 
probably need to reinstall XQuartz with a current version that matches 
your version of R. You are also getting a message saying Java sdk cannot 
be found.


You also appear to be attempting to load the version for R 4.1 while the 
current version of R is 4.2. The R "ecosystem" needs consistency in 
versions of R, XQuartz, Java, and R packages. You will probably get 
better success if you first upgrade R, then reinstall XQuartz,  then 
reinstall or update Java, and finally update all your installed packages 
including rgl and then give it another go.

Finally, this is Rhelp. There is a SIG for R-Mac users. This question 
would have been more on-topic for  that help mailing list.
