Hi Alpha XDO,

Sorry for your issue.

As suggested by Mylenium, please share the following details:

• What are your system specifications (CPU, GPU, RAM, OS)?
• What's the exact version of After Effects you're using: https://community.adobe.com/t5/after-effects-discussions/faq-how-to-find-the-exact-version-of-after-effects-you-re-using/td-p/9972137 
• Do you get any error message or crash report?

Let us know, we're here to help.

Thanks,

Nishu

Without any specific info about your computer, your settings in AE e.g. for caches, your projects and what they contain and so on nobody can tell you much.
