AE to 25.01 - Error/crash related to rendering (and upgraded projects?)

Same here. I can't open few days old project without freezing. It's use all memory and 100% of SSD, many times freeze all the system. I try use it without any plugin, reinstall AE, purge cache, etc. Nothing help!

Do something with it, please becouse I've got a deadline soon and it looks like I can't finish project 😞

The same here. It crashes all the time and is completely useless to work in

What happens if you start After Effects in Safe Mode?

I had to update some third-party plugins for After Effects 2025 version 25.0.1.

Is After Effects 2024 still installed?  You may need to take advantage of being able to have multiple versions installed at the same time to continue working until you figure out what's crashing the new release - be it waiting for an update (25.1 or 25.2, for example) or updating a third-party plugin, add-on, or extension.
