I had a similar issue when moving from 4.0 to 4.1 and reinstalling ggplot2 Basically when loading vctrs it was using the libR.dylib from the R.Framework 4.0 not the 4.1 (and I removed the 4.0)

>library(ggplot2)
       
Error: package or namespace load failed for ‘ggplot2’ in
     dyn.load(file, DLLpath = DLLpath, ...): unable to load shared 
object '/Users/xxxx/Library/R/4.1/library/vctrs/libs/vctrs.so':
           dlopen(/Users/xxxx/Library/R/4.1/library/vctrs/libs/vctrs.so, 6): 
Library not loaded: 
     /Library/Frameworks/R.framework/Versions/4.0/Resources/lib/libR.dylib
Referenced from: /Users/lgzdl/Library/R/4.1/library/vctrs/libs/vctrs.so
Reason: image not found

My temporary solution has been to duplicate the 4.1 and renamed it 4.0. At, least for now > library(vctrs) is not throwing an error! There must be a lingering reference to the R.Framework 4.0? somewhere?

I resolve this problem with latest release R-4.0.2.pkg in www.r-project.org -> Download -> CRAN and select your country.
