Weird variable scope behaviour

[LKuhrmann]

With this simple snippet:

begin
	a =0
	for b in [1,2,3]
		c = a
		a += b
	end
end

I get this weird super weird error behaviour when running the cell the first time after a change: https://github.com/user-attachments/assets/db92a760-1f8f-4381-b4f1-9789fde8916b

(I dont think there should be cryptic errors when you run the cell for the first time after a change but then it runs fine on the second run)
