Installation of pkgconfig on Windows - r

Question

I have successfully installed and loaded readxl package. When I am trying to use the function readxl::read_xlsx(), it throws and error that R cannot find pkgconfig.
I have tried to install this package, but it throws another error, which is presented below:
Installing package into ‘C:/Users/Maintenant Prêt!/Documents/R/win-library/3.6’
(as ‘lib’ is unspecified)
There is a binary version available but the source version is later:
binary source needs_compilation
pkgconfig 2.0.2 2.0.3 FALSE

Warning in install.packages :

I have checked and there are no hidden 00LOCK folders in packages folder, which can conflict with installation. My three suggestions are: (1) either there are no writing rights to this folder (which is wired since all packages are installed normally), (2) or a special symbol ê in the name of the parent folder creates problems.
Does anyone know a workaround?
Here are results of the sessionInfo() and .libPaths():
