Hi @RubinDaPJ,
Thank you for reporting this issue. When the crash report dialog is shown, have you submitted a crash report with your email? That would be very helpful to us as we investigate this issue.
The Animation Composer plug-in is a known source of many crashes, so you might report this to the developer of that plug-in as well, as they may be the ones responsible for a fix.
Thanks again,
- John, After Effects Engineering Team
