I am attempting to launch an Open OnDemand interactive RStudio Server session on Cheaha. When I do, a new tab opens but I can only see a gray screen. Why is this happening and what can be done about it?

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](https://ask.cyberinfrastructure.org/t/how-do-i-locate-hidden-dot-files-on-open-ondemand/2498) `.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.
