Knit button is not creating any html document. When I click, it just creates R makrdown tab and stops. Individual chunks are working fine. I have reinstalled R and R Studio 1.1.442. I have tried on default programs by creating a new document as well. New shiny app document works ok.
It was working fine last week but I had some system update and then it stops working. I have updated all packages through tools but Knit stays on R Markdown tab and giving no error.
