After Effects 2023 memory error when using Camera Lens Blur

I'm getting a lot of memory errors in After Effects 2023 and it appears to be a combination of large images (5000+ pixels in width or height), the Camera Lens Blur effect, and having Multi-Frame Rendering on. 

I have a beefy computer and haven't experienced these errors in the past outside of accidentally setting the Motion Tile effect to it's max values. Has anyone else run into this problem with AE 2023?

Have you found any alternatives to Camera Lens Blur that give results that look just as good and allow for a matte to drive the blur?
I was looking at Fast Bokeh Pro but am curious if you have other suggestions: https://aescripts.com/fast-bokeh/

Windows 11
