Urgent Bug in 2020 - 3D Reference Axis Causes Instant Crash
Turning on the 3D Reference Axis in 2020 causes an automatic crash.
For days I've been trying to figure out why some of my older projects were crashing in 2020 when I opened a comp, and I just realized it's because the 3D Reference Axis was on in those comps.
To recreate the problem, simply add a Camera layer to any comp, and turn on the 3D Reference Axis.
I'm on an iMac running Big Sur, but I get the same results on Catalina, and on a PC running Windows 10.
Please fix ASAP. I have products that clients can't open. It's especially urgent because people on Big Sur like myself can not open the projects in CC 2019, since AE CC 2019 is not compatible with Big Sur (Another MAJOR issue!)

Hi Noel,
Thank you for reporting this crash. It has been fixed as of After Effects 17.7.

This is already fixed in the current AE Beta release (and will be included in the next shipping release).
