I am having the same problem as this previous thread RStudio freezing and QT Webengine eating CPU
I recently updated my rstudio to Version 1.2.1335 and since then I am having trouble opening out some markdowns. When I do open then they freeze Rstudio and the QT Webengine process ramps up to 100% of the CPU. I have to stop this process and Rstudio using the task manager. If I remove the rmd. out of the directory, Rstudio can no longer automatically open it when I restart it, and I can then use Rstudio, but how would I recover the content from the Rmd. and also what is the problem here with QTWebengine?
Any ideas on a fix would be much appreciated.
