Hello, I was using AE earlier today and then all of a sudden my keyframes stopped moving. My layers were not locked, and the only way I could fix it is by deleting a keyframe and then redoing it. The only way I could select a keyframe was by dragging not clicking. But the keyframes are just stuck they won't move. I would select a keyframe, and it won't move. I use AE 2022.
Start by flushing your caches and also check whether you haven't accidentally enabled time-remapping/ time-stretching on these layers. Also of course the usual: Reboot your system, check your graphics driver and input device, check your hardware acceleration settings.
