What is this ? IDE bug?

for some time now , on OSX and Win11 whenever i save a file i get this message in the post-window:

ERROR: Message 'didBecomeKey' not understood.
RECEIVER:
   nil
ARGS:
CALL STACK:
	DoesNotUnderstandError:reportError

		var newCurrent = nil
	< closed FunctionDef >  (no arguments or variables)
	Process:interpretCmdLine
		arg this = <instance of Main>
^^ ERROR: Message 'didBecomeKey' not understood.
RECEIVER: nil

it has no effect except for cluttering the window.
how can i get rid of it ?

Unfortunately, that’s a long standing IDE bug, see Error 'didBecomeKey' when switching IDE tabs · Issue #4813 · supercollider/supercollider · GitHub and scide: Document.current nulled on Class Library Recompile · Issue #4413 · supercollider/supercollider · GitHub
