I would expect it to be possible to rotate the flash slightly in the hot
shoe because of clearances and, if so, it may gradually loosen up that way.
Especially if you apply a gentle turning force (the right way; I bet it's on
a RH thread!) to the lock screw.

That'a what I thought (I am not sure why) -- but checking again you are
correct -- I should apologize for misleading everybody.

I prefer a locking lever. If that gets stuck a few blows with a hammer
will generally do the trick.
