Cannot properly install/load Rcpp

Trying desperately to load and work with Rcpp (well really I am trying to work in the package Seurat which needs Rcpp)

> library(Seurat)  Error: package or namespace load failed for 'Seurat' in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]):   there is no package called 'Rcpp'  In addition: Warning message:  package 'Seurat' was built under R version 4.0.2   > install.packages("Rcpp")  trying URL 'https://cran.rstudio.com/bin/macosx/contrib/4.0/Rcpp_1.0.5.tgz'  Content type 'application/x-gzip' length 3215939 bytes (3.1 MB)  ==================================================  downloaded 3.1 MB      The downloaded binary packages are in      /var/folders/hl/247qzpv55z99f6kgddn95kk80000gn/T//RtmpX3Ovqt/downloaded_packages  > library(Rcpp)  Error: package or namespace load failed for 'Rcpp' in dyn.load(file, DLLpath = DLLpath, ...):   unable to load shared object '/Library/Frameworks/R.framework/Versions/4.0/Resources/library/Rcpp/libs/Rcpp.so':    dlopen(/Library/Frameworks/R.framework/Versions/4.0/Resources/library/Rcpp/libs/Rcpp.so, 6): Symbol not found: _EXTPTR_PTR    Referenced from: /Library/Frameworks/R.framework/Versions/4.0/Resources/library/Rcpp/libs/Rcpp.so    Expected in: /Library/Frameworks/R.framework/Resources/lib/libR.dylib   in /Library/Frameworks/R.framework/Versions/4.0/Resources/library/Rcpp/libs/Rcpp.so  In addition: Warning message:  package 'Rcpp' was built under R version 4.0.2   

I have tried the following

1. restarting, reinstalling -> same errors
2. Making sure Xcode is installed (downloaded from app store)
3. Installed Command Line Tools from terminal with xcode-select --install
4. Installing from source

Can someone please advise? Thanks!
