Problem is solved after DELETING old libraries inside

 

"<user>/documents/R" and in "<user>/library"

 

 

You can see in .libPaths 2 routes but....PowerBI also uses...  "C:\<user>/library"  ....remove old ones from here

  • C:\Program Files\R\R-4.0.2\library

Actually, I had also tried that. I had conflicting versions of packages, and deleted all the old ones and reinstalled everything again to 4.0.2.
It didn't work, so I uninstalled all 4.0.2 again, including R Gui and R Studio and reinstalled all 3.6.3. and it finally worked!
