suddenly can't rearrange layers/drag

I set up my computer without my cintiq after moving, and all the sudden I can’t rearrange layers by dragging them. so if I want a layer to show up above another layer I just can’t do that. I also am not able to rearrange frames by dragging them to new places now either. I don’t know what’s going on with this, as it would always work before, and I can’t get anywhere with my work until this is resolved. If someone knows what’s going on please help!!

here’s a gif of me trying to do so:

Are you using a tablet pen to do this?
Does it also happen when you select with the mouse?

Contact support to assist and investigate.

I have problems both with my tablet pen and mouse
