I Also had problems and rolled back just now. Hopefully this will be fixed in near future!
I just opened a 2017 project under Creators Update and am not seeing any issues. I know these kinds of messages are annoying--would be much better if it was a showstopper bug.

Relancemoody did you clean install the Creators update!? Or you just updated Windows normally!?.
I have the same problem! After upgrade I can not launch AE. I tryed downgrade my graphic drivers, reinstall, using just one monitor but with no luck.
Windows 10 64-bit
I7 - 5820K
NVIDIA GeForce GTX 1060 6GB
Unfortunately I deleted the windows.old folder and I was unable to rollback the windows update.
Of course I had problems with adobe softwares ( some of them would crash immediately after opening and some after uploading a file ) Now I got it fixed without touching windows.
So the solution was rolling back graphic card driver ( in my case Nvidia ) install at least the oldest of 3 latest driver versions.
It worked for me with no restart at all.
Are you still facing this problem? If not, let us know how you solved it. If so, please let us know so we can assist you further.
Unfortunately, I rolled back the Creators update from my system, so I can't really troubleshoot this problem anymore, and am not optimistic that a new update from Adobe will fix it, because all versions of after effects that I tested didn't work for me.
I think Microsoft has done something and I don't know how it may be solved
