Please do the following troubleshooting Go to Preferences > Performance and uncheck Use Graphics Processor and restart Photoshop. If that helps, you can then update the GPU driver, reboot your computer, then re-enable Use Graphics Processor in the Performance Preferences and restart Photoshop.

Hi there, thanks for reaching out. We're sorry to hear that you are experiencing something similar. We're here to help. Which version of Photoshop and operating system are you using?
The download could be due to a network issue if the download is not beginning. Sign out of Creative Cloud and restart the machine. Change the internet connection & sign in again to creative cloud and launch Photoshop as an administrator.
