Just adding: I'm using After Effects 2021 in the lastest version
I also have the same issue. I'm on 22.1.0x34. I can hit spacebar, the comp plays back OK, but the CTI remains static. When I then hit spacebar again to stop, the CTI remains static...for example:
I can then hit the spacebar again, and playback continues from where the CTI is. If, however, I hit spacebar to play, then spacebar to stop, then hit spacebar to play again, nothing happens - no playback at all. I have to scrub the CTI with the mouse for AE to get its act together so I can then play again using spacebar.
I think that AE doesn't realise that it's stopped playing. If I look at the Preview panel, the 'play' icon goes from normal to 'playing' when I first hit the spacebar to start playback. When I then hit the spacebar again to stop playback, the icon remains in its 'playing' state. From then on, any spacebar hits are ignored until I scrub the CTI, which makes the play icon revert to its 'stopped' state.
Sorry for your issue.
Could you share your system specifications (CPU, GPU, RAM, OS)? Also, have you tried resetting the preferences of After Effects? Here's how: https://community.adobe.com/t5/after-effects-discussions/faq-how-to-clean-delete-or-trash-media-cach...
Let us know if it helps.
Really? Two months to an answer and it's not even for me?
Thanks for the suggestions. I updated AE to 22.1.0x36 today, loaded up the same project and the issue remains. I then reset all the prefs and plugin cache (and the prefs were all successfully reset), loaded up that same project again, and the issue is still there, exactly the same. As before, when I first load up AE, and open a comp, everything behaves as expected. Then after a few minutes of working, previewing etc. the problem comes back.
Ryzen 5950X 16 core CPU
Nvidia RTX3090 24GB VRAM, Driver version 472.12 (There is now a newer Nvidia driver - 496.13 - I shall update when I get the chance later today and report back)
Windows 10 Home, OS Build 19043.1288
UPDATE: After updating my Nvidia drivers to the latest version, the AE issues remain the same.
I also have this issue. It must be a bug which they urgently need to fix. The only way I can fix it is by quitting and reopening the program. I have found that it is most likely to occur when switching between AE and Premiere, with dynamicly linked comps.
I solved this problem by increasing my RAM of 8 to 16 GB. I mean, the problem isn't 100% solved, but it has decreased a lot, almost nil. I think if I increase my RAM even more this problem will be solved completely.
Hope this helps you and anyone else with this problem.
