Question:

• When I try to clone a repo in the desktop Stoplight Studio I get the following error: 
  Uncaught (in promise) DOMException: Internal error opening backing store for indexedDB.open.

• When I start desktop Stoplight Studio I see an error in the console of Developer Tools:
  Uncaught (in promise) DOMException: Internal error opening backing store for indexedDB.open.

Environment:

• Desktop Studio (Windows, MAC)

Procedure:

1. Uninstall Studio
2. On a Mac install check that the folder \Users\<username>\Documents\Stoplight Studio\ is gone - if it still exists delete it
3. For a Windows install check that the folder C:\Users\<username>\Documents\Stoplight Studio\ is gone - if it still exists delete it (on Windows there may be additional folders under the C:\Users\<username>\Roaming folder that need to be deleted)
4. Reinstall Studio
