The Problem was is I not all my bones was connected properly, I had to remake the skeleton but I learnt how the armature works in Blender (kinda haha)
Since my bones werent properly connected it counted as seperate roots and as seen in 1.PNG, it talks about ‘multiple roots’ and how it doesnt support it, which I believe is what its talking about, and what I mentioned before about the bones being not connected so mustve counted as seperate ‘roots’
I hope people can understand this but im bad at explaining and not very experienced myself but I hope they get atleast a vague idea what I mean
