Blender stopped recording the rotation keyframes I'm using Blender 2.92 and I've made an animation in around 110 frames using the Auto Key option. But suddenly Blender stopped adding keyframes upon rotating the controllers. It allows me to animate the movement only. I can't even animate the scale for the controllers that have the scale functionality either. I am using the Vincent model rigged in Blenrig. I checked the channels, they're not locked, restarted my computer, but no joy.
Moreover, I can animate the rotation by using the Rotation channels in the N panel.
File attached for your kind support.

your end frame is at 113 so Blender will not autokey your animation over this end frame. If you raise this to ...e.g. 1000 you can auto - keyframe a bit more time.
