After having issues with installing CRAN packages and no solutions found I uninstalled and then re-installed the entire setup (both R and RStudio).
Now I cant even install tidyverse again.
I tried to change R and RStudio location and give full control on the security settings and obviously running as administrator..
I have ASUS, running Windows 10. I dont have any firewall activaed at the moment..
For the RStudio folks out here.. this is some really bad ■■■■ that happens, I really hope to solve this but it makes life very hard for novices to start their journey /:
