Why do I get an error when running ggplot2 in R 3.5.0?

I am trying to run ggplot2 in R 3.5.0 but it is giving the following error. I can only use this version since it is the only approved at my company.
I have tried removing the package e reinstalling different version but only the ggplot2 version 3.2.0 successfully installed. I tried newer and older versions and it does not install. I am using a Windows computer.
library(ggplot2)
Error: package or namespace load failed for ‘ggplot2’ in rbind(info, getNamespaceInfo(env, "S3methods")):
number of columns of matrices must match (see arg 2)
In addition: Warning message:
package ‘ggplot2’ was built under R version 3.5.3

unable to install "dplyr" package in R

While installing the dplyr package I am getting the error in RStudio, whereas if I am trying to install the same in R, I ma getting an error saying:
package dplyr is not available (for R version 3.5.2)
this is the error I am getting in RStudio:
Error: package or namespace load failed for ‘dplyr’ in library.dynam(lib, package, package.lib):
DLL ‘bindrcpp’ not found: maybe not installed for this architecture?
Have you checked what version of R you are using? Just use the
version
command. If it's less than 3.5.2 you might find that libraries dplyr requires aren't being installed and that's why it's failing to find, for example, bindrcpp.
In my corporate environment I had a very similar issue trying to install dplyr after our tech support operation upgraded my PC, but installed a too-old version of R.

Error R version installed with different internals, have installed ggplot many times

Whenever I try to load ggplot the following error comes:
Error: package or namespace load failed for ‘ggplot2’:
package ‘scales’ was installed by an R version with different internals; it needs to be reinstalled for use with this R version

Installing readtext package

I cannot install the readtext package, and I have tried two ways:
when trying 'install.packages (readtext)' a message is displayed saying that this is not available for R version 3.3.3
When trying to install it from github through devtools, it shows up the following message:
ERROR: dependency 'stringi' is not available for package 'readtext'
* removing [readtext from my library]
Error: Command failed (1)
This is weird because the stringr package is installed...
Thanks

Problems trying to install package in R

I am having problems trying to install the nnet package in R. The download seems to be ok, but when I load the library it states
namespace ‘nnet’ is imported by ‘car’, ‘effects’ so cannot be unloaded
In addition: Warning message:
package ‘nnet’ was built under R version 3.2.5
Error in library(nnet) : Package ‘nnet’ version 7.3.11 cannot be unloaded
I tried reading other topics which suggest using remove.packages on car and effects. However I tried this and I am still unable to install
Thanks for the help
Try unloadNamespace('effects') before trying library(nnet).
