Hello,
Have you checked it is in the PATH system variable?
After installing Rtools you must edit the Windows PATH. It not, the
system will still find the older Rtools version.
No, well as long as we are talking about base R, which we should be
talking about on this list. R automatically adds Rtools to PATH when it
is needed there. R knows which version of Rtools it needs (R 4.2 uses
Rtools42, R 4.3 uses Rtools43, R-devel currently uses Rtools43 but that
will change before R 4.4 is released).
More details are in
https://cran.r-project.org/bin/windows/base/howto-R-4.3.html

Hope this helps,
