Trouble installing DevTools in RStudio

I'm trying to install DevTools using RStudio with my R version 4.0.5. I install the packages in RStudio from the CRAN repository, and everything looks fine until the following comes up:

enter image description here

obviously processx is a dependency of DevTools. The trouble seems to start when the system tries to use the 'as' executable in RTools. It can't seem to use it but it's definitely there and in the same folder as my gcc executable:

My 'as' executable in RTools. Path it's on can be seen at top.

I've already added the following values to the following environment variables:

Variable Value
Path C:\Program Files\R\R-4.0.5\bin;C:\rtools42\usr\bin;
BINPREF C:\rtools42\x86_64-w64-mingw32.static.posix\bin\
R_HOME C:\Program Files\R\R-4.0.5\library\base\R\Rprofile
R_LIBS_USER C:\Program Files\RPackages
R_USER C:\Program Files\R\R-4.0.5
RTOOLS42_HOME C:\rtools42

I'm wondering what to try next?

EDIT: See below for results of GCC -v as suggested:

Edit 2: The original issue was fixed by updating my R version, but now as I try to install a package called "markdown" I'm encountering this next issue:

Edit 3: here is the output from my sessioninfo():

I believe you use the wrong R and RTools combination:

Use Rtools 4.0 for any R Version below R 4.2.0 as the following page suggests:
