We're sorry for the trouble. Can you try switching the graphics card to Standard VGA and then test the issue? You may follow this path: Open Device Manager > Select Display adapters > Right-click the GPU > Select Update Driver > Browse my computer for driver software > Let me pick from a list of available drivers on my computer > Select Microsoft Display Adapter > Next > OK
If this doesn't work try sign out and back into Creative Cloud account.
Also, try reinstalling the Rush. This may fix this issue.
