This is part of the problems I have had in the past... I thought it was my internet, but now I have a much better fiber provider and last night and today, I am still unable to update any of my programs, except, Bridge and when I try to load it, it is "unresponsive"
I had a similar issue. Make sure that you have all Windows updates that are available. The one thing that was causing it for me, believe it or not, was that I needed to do a clean installation of the latest Studio graphics driver from the NVIDIA website. After doing that and restarting, all was OK.

4. Start again from the top by reinstalling the Creative Cloud and your tools.
If still no luck, then the route people often take instead is to request/use the direct download links for theCC Desktop appor for the2020 Creative Cloud appsthemselves – whatever you need. With those, you can download offline installers which are industry-standard .exe/.dmg files for Windows/macOS.
It is frequently reported those standalone installers will download much faster (and complete!) over the same Internet connection than when using the CC Desktop app... nobody's really sure why.
