This is something that RStudio (not R itself!) does, but it shouldn't
be failing. Here's what seems to be failing for you [*]:

   # prepare directory for discovery of available packages
   dir <- tempfile("rstudio-available-packages-")
   dir.create(dir, showWarnings = FALSE)

   # create a file in that directory
   saveRDS(Sys.time(), file = file.path(dir, "time.rds"))
   # (This doesn't fail because we keep executing the function, so the
   # directory must exist!) 

   # move there
   owd <- setwd(dir) # this somehow fails

Is it an option to disable OneDrive for the home directory? It's
clearly doing something terrible to your temporary files. If not, it
should be possible to create a separate temporary directory on your
computer (the path must not contain spaces) and list it in the
.Renviron file in the home directory as the TMPDIR variable:

TMPDIR=C:/my/R/temp/directory

See help(Startup) for more information on .Renviron.

Alternatively, we may try to perform some debugging. If you set
options(error = recover) and run .rs.availablePackages() again, it
should fail and give you a debugger prompt. Choose the deepest option
in the call stack and try to find out the value of the `dir` variable.
Does dir.exists(dir) still return TRUE? Does setwd(dir) still fail? Can
you open the directory in the Windows Explorer?

The last but not the least, do you see some of the same problems if you
launch Rgui.exe instead of RStudio?

Hi,

I uninstalled onedrive, I eliminated all the folders and then reinstalled R
and RStudio... but it is RStudio the one creating a folder
called C:\Users\Ana\OneDrive - Universidad Complutense de Madrid
(UCM)\Documentos.

This is what I obtained with the debugging

Error in setwd(dir) : no es posible cambiar el directorio de trabajo

Does Rgui.exe use a different home directory from RStudio? Perhaps you
need not to reinstall RStudio (which deletes and recreates the program
files which aren't damaged) but to wipe the profile (the settings
somewhere under %APPDATA% or %LOCALAPPDATA%), but it pays to be extra
careful about these directories. People at
<https://community.rstudio.com/> may know more about that.

I'm afraid I don't know how to disable OneDrive on a Windows 10
installation. If your university has a Microsoft support contract, it
could be worth asking the Microsoft representative to fix OneDrive so
that temporary files would work on it and telling them the steps to
reproduce the problem.

What is the value of `dir` at this point? (What does print(dir) say?)
Can you open this directory in Windows Explorer?

If possible, could you please set your mailer to compose messages in
plain text instead of HTML? The plain text versions of your messages
that your mailer generates from the HTML messages are somewhat mangled:
