Adobe CC no longer working after Windows 10 update 2004
So basically, ever since I got the new Windows 10 2020 May Update, I've been getting an error whenever I open CC saying:
Adobe Creative Cloud is needed to solve this problem. However, it is missing or damaged. Please download and install a new copy of Creative Cloud from 'http://www.adobe.com/go/adobecreativecloudapp'
I've tried repairing the installation, I've uninstalled and reinstalled CC at least 15 times (also using the Adobe Cleaner application and manually deleting the rest of the adobe folders before each installation), I've had an adobe support guy controlling my computer for 1.5 hours and made no progress, and I've tried every. single. solution. from the adobe help site and community.
Still no success.
I suspect the latest version of windows broke something, because no matter what I do, CC just doesn't work.
Any help would be much appreciated, although I think this might be an OS problem.
Cheers.
Jim
