Help Installing R Studio on MAC M1 OS

Hi there, I'm new to MAC M1 OS & new to R & new to this community.
I am trying to install R Studio on my M1 OS.
I get this error message:
Error reading R script (), system error 2 (No such file or directory); Unable to find libR.dylib in expected locationswithin R Home directory /Library/Frameworks/R.framework/Resources

I've obtained a Rosetta license but Rosetta also won't install.
Couldn't get Quartz to do anything either.
My IT dept can't help. Can anyone help this techno rookie?
