Keying set failed to insert any keyframes
every time I try to insert a key frame using 'I', I get the error "Keying set failed to insert any keyframes". I haven't (knowingly) changed any settings, what could it be?
edit - I have managed to add a keyframe by changing some settings, but I don't get that menu you show when you press 'I'. I am using BLender 2.83
