I mistakenly enabled these arrow lines showing white space, how do we turn it on or off?

Hi @bipal_maharjan, Thanks for reaching out about this!

I’m not entirely sure, but it seems like you might be seeing guides on your canvas. Could you try pressing [Shift + R] to see if that toggles the visibility of the guides?
For more details on adding or managing guides, you can check out here: Add guides to the canvas or frames
