I have the same problem once I hit the spacebar to preview the start loop for just two frames and nothing happened.

For anyone on mac still having this issue and an ultra high resolution monitor (4k or more) connected to the machine, I solved it by going to the get info window for after effects and checking open in low resolution.

You will see the interface become a little fuzzy but it's negligible, however this annoying problem hasn't happened ever since.

I'm using AE 22.4.0 (build 56) on an iMac Pro running OS 12.4. I'm having this preview issue too. It's been driving me crazy. I just updated everything yesterday and it seemed to go away for an hour or so. Today it's just as bad as ever. It happens all the time. Is there really no fix for this? Looking through the boards this seems to have been an issue for years.

I'm having this issue as well, though it started in the past 6 months or so for me. Preview gets stuck and requires many presses of the spacebar to get it to stop looping. It does eventually stop, but it's super frustrating to have to press so many times, and it's so unreliable how many times are required. Sometimes 2, sometimes 7. Then sometimes you miss it and it starts previewing again and you're back at square one. Infuriating to say the least.

AE 23.3.0 (Build 107)

still a HUGE problem. This is a workflow killer. This should be such a high priority - something that has been broken for well over a year? I don't even understand how to get meaningful support at this point. Every time I talk to adobe support they just basically tell me to uninstall everything and start from scratch and not use any 3rd party plugins. How is that helpful? I can't wipe my machine clean all the time in the middle of projects and there's no professional out there that doesn't use 3rd party plugins. It's comical how slow AE interface runs on my 2017 imac pro with maxxed out specs (128gb ram, 18 core, radeon pro vega 64 16gb). This machine cost $12000 a few years ago - it's not a dinosaur, but AE runs like I'm trying to force the last bit of juice out of my 1998 imac G3.

This issue continues like so many others...

I'm also having this issue. Version 22.0.0, build 111. It's been going on for a while, though...
