Adobe Animate CC Stage/Canvas Scaling Stuck

I recently downloaded the most recent version of Adobe Animate CC for the first time, and I've been having incredible issues with the stage. I've restarted Animate, my computer, ran the program as an administrator, etc. The issue is that when I create a new document, the stage gets stuck on the right side of the workspace, with some of it getting cut off by the toolbars. This isn't an issue of the "Pastebar" option, because the canvas just won't move left. I've proved a screenshot below of the extent to which the canvas can move left. I could use help as soon as possible, as I have a very large project to work on with Flash.
