.libPaths() raising error because Documents folder could not be found by R

The output I get is the following:

> Sys.getenv("R_LIBS_USER")
[1] "C:/Users/I�igo/Documents/R/win-library/4.1"
Warning message:
In normalizePath(path.expand(path), winslash, mustWork) :
  path[1]="C:/Users/Iñigo/Documents": El sistema no puede encontrar la ruta especificada

So I guess I have to change that location because RStudio is taking it as the default library location for my user?
