  • try Windows > Reset Windows to Factory Settings
  • Is there any way to do it without a reset? I can't back up the rest of my files at the moment
  • But it will only reset your windows, it won't close your opened files.
  • I have no clue. Just a suggestion. Maybe try Oracle support/community forum?
  • find the connections.xml file and delete it - it's probably been corrupted - only do this if the Reset Windows to Factory Settings doesn't fix it first. BTW, this is not MSFT Windows/format/re-install, it's the WINDOWS menu in SQLDev, it has a Reset item which refreshes the desktop layout of SQLDev
  • This works and doesn't forget all connections credentials
  • You don't even have to re-install - I did steps 1, 2, and 3, then simply re-launched sqldeveloper; the folders you deleted will be re-created; then just place your o.jdeveloper.db.connection.xxxx in the correct location. And re-launch sqldeveloper again.
