Thank you for reporting this issue, and sorry to hear that you're experiencing this issue. Thank you for including the version info and your system specs!
On a Windows system with an Nvidia GPU, I tried rendering a comp using the Camera Lens Blur effect on HD footage without a Blur Map layer set, both for preview and through the Render Queue, but I didn't experience any crashes or failures to render. Would you be able to share your project and assets with us so that we can diagnose what might be failing? If not, a screen share of the issue occurring would be extremely helpful as well.
Additionally, does the Crash Report dialog show up when you crash? If you submit a crash report with your email, that will also help us to further investigate the issue.
Thanks for reporting this issue and for any further information you can provide,
- John, After Effects Engineering Team
