R has problems working with network drives, I would recommend setting your package library in a local folder instead.

You can change the default library folder by setting your R_LIBS_SITE environmental variable on a .Reviron or .Rprofile file

# In a .Renviron file you can set it by adding this line
R_LIBS_SITE="C:\\Program Files\\R\\R-4.0.3\\library"

For a more detailed explanation, you can read this blog post

thank you . it works with changing the local library
