Here’s some pics...the strings are way too high near the bridge why???
the nut is a larger fret than the others ....it’s perfect at fret 1-4 and then rises steeply ... the bridge has to be sit that high so the first few frets don’t fret out ..the neck has a very slight break angle and is straight as a can be. There is 1/4. Inch price of wood above the body ....higher action at the bridge is fine but not this high.....

I should have mentioned that the zero fret is easily replaced with a conventional nut, just a little bit of surgery. Just make sure the front edge of the new nut is positioned so that it matches where the string leaves the zero fret. If the fret has a nice crown that will be in its center, over the slot.
But I do not think the nut is the issue.

Hi, a photo of the complete instrument, side on, would make it easier to diagnose the problem.
But the zero fret is normally a next size or two up to give clearance over the fingerboard frets. The lay of the strings off of the top of the box looks good, bridge height look good.
Could be neck is bowed up or set into the box at the wrong angle.
Use a straitedge to check.
Fingerboard best at a 1/4" above box top. I have my bridges at 1/2" to 5/8" high. String height above frets differs between slide or fretting styles.

It looks like when you cut the neck out it has a lot of back angle. What does it look like if you put a straight edge on top of the frets and over the box. Does the box angle down towards the bridge or is it parallel with the fretboard? If it has a lot of back angle there is not much you can do besides having a tall bridge. I like not having the strings too close to the box.
