Since an upgrade of windows 10 to version 1903, Sourcetree's external diff no longer works. It was fine until then.
(Other colleagues have has the same experience and now we only have one team member who is still on an earlier windows10 release... waiting for their sourcetree to get zapped with the next update!)
I have tried switching the diff tool between KDiff3 and AraxisMerge, but neither will launch.
From reading older posts on this problem, I have tried removing the escaping \ from the diff arguments, but nothing seems to make it any better.
Please can anyone suggest a cause/solution?
