When I tried to load DeSeq2, it gave the following error:

> library(DESeq2)
Loading required package: GenomicRanges
Error in value[[3L]](cond) : 
  Package ‘GenomicRanges’ version 1.50.1 cannot be unloaded:

In addition: Warning messages:

2: package ‘GenomicRanges’ was built under R version 4.2.2

If I try to install GenomicRanges, I got the following errors:

A version of this package for your version of R might be available elsewhere,
see the ideas at
https://cran.r-project.org/doc/manuals/r-patched/R-admin.html#Installing-packages

Thanks for any help.

You should not try to install packages when you already have packages loaded. Instead, start R, then load the BiocManager package, and then install.

That said, you should simply be able to restart R and it should work. And also, the package is GenomicRanges, not GenomicRange.
