after effects doesn't open, if open crass message came slove this problem.

Hi, sorry to hear about the issue. To help, could you share a bit more information?

1. A screenshot of the exact crash/error message you see.

2. Your exact After Effects version and OS.

3. When does the crash happen — as soon as you double-click the AE icon, or after the splash screen?

4. Did anything change recently (a Windows/macOS update, a new plugin, a driver update)?

Once we have those, we can help figure out what's going on.

Thanks,

Nishu
