Pano sunroof - roller blind tangled at rear

I have a 2012 Superb Mk 2 Combi (Estate) with the panoramic sunroof.

The roller blind (sun screen) has got jammed or tangled or somehow detached at the back where it’s meant to roll up. It can’t now close, and if opened the blind doesn’t roll up - it droops down instead. It makes a load of clicking noises as if there’s a spring that’s broken or displaced. You can also see the roll of fabric is not neatly rolled up.

Is this fixable, or is it going to need a replacement blind?

Please note: to avoid confusion, I’m talking about the rolling sun screen that’s part of the panoramic sunroof, not the blind over the luggage area.

Thanks!
