How do I fix this error being caused by the 'openair' package?

Question

I am attempting to pull data from the U.S. EPA using the 'openair' package. I have installed 'interp' and 'openair', but I continue to get this error:
Error: package or namespace load failed for ‘openair’ in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]): there is no package called ‘interp’

I am currently using the most up to date version of Rstudio and I have updated all of my packages as well. I have also tried removing the packages to re-install them, but I get this error when I try to remove the packages: Removing package from ‘/Library/Frameworks/R.framework/Versions/4.2/Resources/library’ (as ‘lib’ is unspecified) Removing package from ‘/Library/Frameworks/R.framework/Versions/4.2/Resources/library’ (as ‘lib’ is unspecified) Error in remove.packages : there is no package called ‘interp’
Any ideas on how I can solve this issue?
