Most commonly, delays in launching Open OnDemand RStudio Server are caused by a large quantities of files referenced in the .rstudio directory in the home directory. This can also commonly occur when a large amount of data was loaded in the workspace in your previous RStudio session. To resolve the issue, you’ll need to locate the hidden directory .rstudio in your $HOME folder. Once you’ve found it, delete it, then try recreating your job.
For rstudio version >=1.4, the RStudio session data is stored in .local/share/rstudio.
Warning! Deleting the .rstudio directory will delete the workspace you had open, including any scripts that were unsaved. Saved scripts will be fine.
