Rstudio 1.2.xxxx won't startup properly

Error Information:

Description of issue
RStudio preview 1.2.xxxx hangs on a white screen when I start it. After hitting reload in the drop down menu the IDE shows up but hangs upon any click and won't respond. Possible culprits are

  • most recent version of MacOS Mojave beta build (10.14.4 Beta (18E215a)) to which I recently updated or
  • the attempt to use new features of reticulate package integration to execute Python code.

Rstudio preview used to work normally before updating MacOS to recent beta and attempting using reticulate.

Attempted steps taken to fix

This is a known issue with the latest Mojave beta:
