What options are there to have a Surface repaired and how expensive would that be? Will?

I know that it was stupid and that I have to be more careful, especially on such expensive things, so please don't tell me that anymore. I'm just trying to find out what I can do now.

A few weeks ago, my Asus Surface Laptop, which I use for university, fell off my bed, but it wasn't particularly high, but it was enough. The laptop itself continues to work perfectly in terms of all functions and has no scratches or anything else. Only the surface function no longer works, so the screen neither reacts to touch nor to my Asus sketchpen. Before that, everything worked perfectly.

Surface is generally sensitive, I suspect that something has slipped or jumped off on the screen, but I can't fix it myself. So far I haven't found a case like mine online to compare prices, etc. Does anyone know their way around or have they already had such a case? If so, how much would you estimate the repair costs?

Has the digitizer said goodbye? Off to the repair.
