I want to add that happens only in one project, while other renders progressing normally.
When I try to render my project, it shows a message called "After Effects CC 2017 has stopped working".
are you using 14.0.1 ? if not, you should update
so you say it's only in this project? try to isolate the problem. does it happen at a specific time? with a specific render settings? try removing comps, layers, effects and see when are you able to stop it from crashing. come back to us with more full system information.
Ok, I try to update, but now it happens for no reason, not only at the render time.
I always use the same renders, Quicktime - H.264
Sorry to hear about your troubles. Did you ever solve this issue? Have you tried importing the old project into a new one and exporting from that? Let us know what you tried and if anything worked, or if you still need help.
