Hm this sounds like a mystery to get solved. Like there's something you will enjoy you just don't know it yet. Sometimes my old hobbies don't interest me anymore, and sometimes they would but I'm too depressed to connect with them.
You sound like me at the moment, so my suggestions may be out of reach - I am having trouble forcing myself to do anything but at other times when I still managed to find some willpower I would do things like the following:
I sometimes sign up for an evening class - I've tried pottery, life-drawing, boxing, modern dance... All of them started out with my having to drag myself to them and after a few weeks I looked forward to them. You don't have to know that you like something already to try it.
You could also go to your local library and look thru the craft section, the art section, the DIY section... See if anything catches your eye.
What about shifting some things around at home, changing up the placement of your furniture - that might make you realize you want to make some creative changes as well.
And one thing that sounds silly but can really work is putting on some fun music and forcing yourself to jump, dance, shake your head, shake your arms, just flail about trying to shake some silliness into your body. For me it can help remind me that - here I am and I'm alive. Usually ends up making me laugh and maybe you can find someone else to join in.
