AE 17.0 RAM Preview unresponsive / stuck
RAM Preview speed has improved but the entire program becomes unresponsive to clicks, spacebar, Num0, ESC, etc. Playback continues on loop and the only way I've found to regain control is to minimize/maximize AE.

This is fixed in After Effects 17.0.1, released last night. Please update and let us know if you’re still seeing any issues.

Just updated to the last version 17.1.1 it is still there for me, it happens on every project even new ones. Making After Effects unusable..

Same problem with 17.1 here. Makes AE CC 2020 totally unusable for me.

This is still an issue, 17.1. Just updated, and I still have the issue. Minimizing the window via keyboard shortcuts or closing the window via task manager is the only way to fix it. Intermittent issue.

I agree with Bjorn, this problem seems to be back. Just updated to 17.0.06.

Yep. Me too. Loops round and round and round and round. Hitting minimize and waiting a few seconds seems to stop it.

I'm seeing the same thing, but without the improvement to preview speed 🙄
I have to force-close the program in order to get it to stop.

Are there specific steps to reproduce this? Also, what is your system configuration?

Same problem here. Audio in particular just loops forever with no way to stop it.
