Hello ! This bug is still here ! I’m using Unity 2022.1.16f1 for a project with my students. The school installed this version. If you try to add a keyframe (in a animation) changing the sprite of a sprite renderer, it will give this error.

The solution i found is to manually add a keyframe of type sprite renderer type. Then, if you try to modify the sprite again, the keyframe will add correctly. There is no sense …

I hope it’s fixed in the other versions !
