Suddenly any attempt to update the workspace, open the configuration window, etc. is throwing this error: "An item with the same key has already been added"
Tried switching to the old GUI, as a colleague said that solved this same issue for them awhile back, but to no avail. Restarting doesn't solve it, nor does undoing all pending changes.
Let me know what details about my setup you need to be able to help me get back up and running.
All help greatly appreciated.
