Adobe CC apps crashing when trying to launch

[fayp83157437]

Yesterday at work everything was working fine, but today after trying to load up After Effects / Photoshop / Illustrator I get an error message saying it quit unexpectedly.

I haven't updated or added anything so I'm not sure why it has suddenly stopped working.

Tried looking for a solution and I have tried:

Restarting, re-installing the apps and creative cloud, and clearing my preferences. None of these have worked.

Can anyone help with a solution? Need to get this working so I can continue with work.

My Illustrator CC 2018 was behaving badly so I tried to open the desktop app for CC, to check for updates. That app hung and refused to launch after two restarts and a shut down. Headed to Support...

Which Operating System?

Did your computer receive any recent OS updates?

[fayp83157437]

MacOS  High sierra

Version 10.13.16

I did update it about a week ago but it didn't effect any of my apps when I first updated it.

So after a morning on a support chat/screen share with adobe to fix my problem, I'm told it'll work since the support guy changed some of the files. It didn't work.

Added to my problem instead, now all my apps don't say "open" and only say "buy now" even though I have a subscription, plus the crashes kept happening.

Out of options I completely reset my Mac, re-installed everything and now it works.
