After Effects 2026 and 2027 freeze when changing composition settings after latest update

Since yesterday's update, After Effects has started freezing when I change composition settings, specifically:

Affected versions:

The issue happens in both versions.

What happens:

When I modify the frame rate or composition size, After Effects freezes and stops responding.

The only way I have found to recover is:

Go to the After Effects icon in the Windows taskbar.
Close the application using the taskbar.
After attempting to close it, I can click Cancel in the composition settings dialog.
After that, After Effects becomes responsive again and I can continue working.

This is unusual because the application appears frozen, but clicking Cancel after attempting to close it restores normal operation.

When did it start?

The issue started immediately after installing the latest update on November 12, 2026.

It affects both After Effects 2026 and 2027.

Computer specifications:

OS: Windows 11 Pro 25H2
CPU: Intel Core Ultra 9
Motherboard: ASUS TUF Gaming Z890-PLUS
GPU: ASUS ProArt NVIDIA GeForce RTX 4070 Ti ( will update to new driver after this)
RAM: 128 GB DDR5
Storage: Samsung 990 PRO 2 TB NVMe SSD

Expected behavior:

Composition settings should update normally without freezing or requiring the application to be closed.

Please investigate whether the latest update introduced a bug related to changing composition settings in After Effects 2026 and 2027.

Hi, thanks for the detailed report. I tested changing composition settings on my end but couldn’t reproduce the freeze.

Could you try the same steps in Safe Mode with third-party plug-ins disabled and let us know if the issue still happens? Here’s how to start After Effects in Safe Mode.

Let me know how it goes.

Thanks,
Nishu
