For those of you still searching for a solution, I would like to share a workaround that I have discovered. It's not ideal, but saves me from having the completely close CA and reopen the plan. This workaround is only for those that have multiple monitors.
If your cursor disappears on the working screen, but is still visible around the upper toolbars, click and drag the working screen/tab to another monitor. Now, your cursor may reappear and you can close the window that is frozen, on the original monitor. Hope this helps.
As a quick update to this thread, I also went through an entire troubleshooting process directly with Nvidia. Nothing changed and the issue persists.
