I have to repair Creative Cloud daily (well, it works on the days when I don't have a project due or a serious need for any of its programs). Sometimes it appears completely blank (as in the attachment); sometimes the notice about needing repair appears.
Sometimes it takes as many as twenty tries to get Indesign to load (Photoshop is slightly better). I have deleted the preferences, cleared the cache, uninstalled and reinstalled the program. As with all of Creative Cloud, it seems to "know" when I don't have serious need for it and then will start up beautifully. But if there's a deadline, forget it. I repair Creative Cloud when Indesign isn't starting, but that doesn't always help either.
I am now using a MAC with the Monterey system, but this problem has been occurring since I installed Creative Cloud some time ago.
I don't know what "improvements" to the program have caused these repeating and maddening problems.
first, reset the cc app:
to reset the cc desktop app, make sure it's in the foreground, then press:
Win: Ctrl + Alt + R
Mac: Cmd + Opt + R
if that fails, try to repair
if that fails go ahead and uninstall using the correct uninstaller from https://helpx.adobe.com/creative-cloud/help/uninstall-creative-cloud-desktop-app.html#sa_src=web-mes... and then reinstall
if that fails, do a clean cc install following each applicable step:
uninstall every cc app including preferences, https://helpx.adobe.com/creative-cloud/help/uninstall-remove-app.html
then uninstall the cc desktop app, again using the correct uninstaller, https://helpx.adobe.com/creative-cloud/help/uninstall-creative-cloud-desktop-app.html#sa_src=web-mes...
clean your computer of cc files per http://www.adobe.com/support/contact/cscleanertool.html
restart your computer (don't skip this)
reinstall the cc desktop app, https://creativecloud.adobe.com/apps/all/desktop?action=install&source=apps&productId=creative-cloud
if you're unable to download the cc desktop app at this stage, use the link at the bottom of the page at https://helpx.adobe.com/download-install/kb/creative-cloud-desktop-app-download.html
use the desktop app to install your cc programs/trials
If possible for testing, create a new Administrator user account and login to same and observe whether if it works fine there without any isue or still same.
You can also start the computer in Safe Mode and/or run diagnostics to see if there is a hardware problem.
I did all these things. The problem persists. Now Creative Cloud opens with a blank screen and force quitting is the only way to escape it.
