this issue has been posted in numerous threads. all appear to be Windows 10. still no sign of a proper solution - there is some lack of feedback to the responses that are offered. please review this thread and see if there is a fix for you there: Re: After Effects CC 2017 Won't Open! Shows Empty Box!
Here are other threads with reports of this problem but currently no information or feedback provided by OP:
if the solution offered in the link above does not work, I would suggest seeing if you can update your Display driver through the manufacturer website.
in any case, please come back with results so we can update the rest.
Also, if you uninstall After Effects CC 2017 then install it, it may give you the 14.0 version and give you the option to update it. That's how it used to work with earlier versions, but I haven't had to try it, so I don't know if that's how it works anymore.
This bug should be fixed in the update that released today. See Tim's post about it here. The After Effects CC 2017 update to version 14.2 is rolling out worldwide. It may take a day or so to show up for you depending on where you live. You also may need to log out and back in to your CC app or other funky things to get it to show up.
Please let us know if this works for you.
