If that is the crack on the left side of your fade out in the last picture, it is not a fatal crack.
Looks like your handle isn't glued on. Take your handle off, soak the crack with super glue, clamp it closed until the super glue dries, glue, not wrap, a new handle piece on but extend it further down your limb and feather it into your limb with no abrupt angles.
I like to glue a couple very thin pieces on first when I replace a handle. These will flex with the limbs and won't pop the glue joint loose.
As the final part of the fix you can glue a thin strip on the back of your handle the same length as the belly piece to make a crack sandwich.
Broken bow recovery is a great learning tool.
Here is how you should feather your handle into the limbs, no abrupt angles.
