In my recent project work, I did something that resulted in the disappearance of the 3D axis in the viewport of the "Layout" workspace, not only that all that four buttons(including zoom thingy, move, camera and projection buttons). I am not sure what lead to this. Weirdly, both 3D axis and 4 buttons exist in all workspaces except in "Layout".(screenshot attached)
I googled to check the problem and found a similar issue caused using transform hotkey(devtalk blender). Although I didn't do anything similar.
Is this a bug? How can I resolve this?
