Can you include the Stardog Studio logs? They're located at ~/Library/Logs/Stardog\ Studio/log.log for MacOS and %USERPROFILE%\AppData\Roaming\Stardog Studio\log.log on Windows.
We believe we've identified the bug here (it is likely specific to Stardogs < 7.x) and will be releasing a Studio update shortly to fix it. Thanks for the report, Tim!
Thanks! The tail of the log from my latest attempt is below. I also noticed that each time I start Studio, it is asking me if I want the tour, not remembering that I had declined previously.
Also, is that an option I see in the configuration to disable auto-update of Studio? I hope so - been asking for that option.
