namespace ‘rlang’ 0.4.6 is already loaded, but >= 0.4.7 is required

I ran this command:
library(SnapATAC)
and got this error:

Error: package or namespace load failed for ‘SnapATAC’ in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]):
namespace ‘rlang’ 0.4.6 is already loaded, but >= 0.4.7 is required
Traceback:

1. library(SnapATAC)
2. tryCatch({
   . attr(package, "LibPath") <- which.lib.loc
   . ns <- loadNamespace(package, lib.loc)
   . env <- attachNamespace(ns, pos = pos, deps)
   . }, error = function(e) {
   . P <- if (!is.null(cc <- conditionCall(e)))
   . paste(" in", deparse(cc)[1L])
   . else ""
   . msg <- gettextf("package or namespace load failed for %s%s:\n %s",
   . sQuote(package), P, conditionMessage(e))
   . if (logical.return)
   . message(paste("Error:", msg), domain = NA)
   . else stop(msg, call. = FALSE, domain = NA)
   . })
3. tryCatchList(expr, classes, parentenv, handlers)
4. tryCatchOne(expr, names, parentenv, handlers[[1L]])
5. value[3L]
6. stop(msg, call. = FALSE, domain = NA)

Any ideas? I've already installed rlang

OK I solved this problem by quitting all R kernels, and reinstalling 'rlang' outside Dev mode
