“Cannot edit the object, which is in use by ‘username’ at Site ‘configmgr site’

If you've ever been in the middle of editing an application and had the ConfigMgr console crash, you've likely seen this message.

myitforum.com has a quick and easy way to unlock the object so you can get back to editing! Article is linked below, but here are the two queries to run in SQL Server Management Studio:

This query gets the ID of the locked object:
select * from SEDO_LockState where LockStateID <> 0

This query will delete the locked object, allowing you to get access again:
DELETE from SEDO_LockState where LockID = ‘<LockID of the record identified in the previous query>’
