Hello and welcome to my second puzzle ever!!!
I did this one in about three hours and I'm both astonished and delighted to say that is has a unique solution! Enjoy!
Rules:
Normal Sudoku rules apply. The digits along a thermometer increase from the bulb end.
Anti-Knight: Identical digits may not appear one knight's move away from each other.
Highlighted cells are anti-double-knight cells. Identical digits may not appear any 2 knight's moves away from those cells. (Note: those knights moves needn't be in the same direction, as is the case for some chess variant pieces)
Solution code: Box 9 (reading order)

OH, phew. You had me quite nervous there. Glad you liked the puzzle though.

By collapses, I just mean resolves. All the remaining pieces quickly fall into place at that point.

Marshal on Mars, this is quite distressing information seeing as I triple checked the solution for any contradictions. Could you explain how it collapses?

There's one tricky bit near the end (that then collapses the puzzle), but otherwise not that challenging. 3-star difficulty in my view, but others' mileage may vary.
Fun puzzle overall.

I'm not quite familiar with the courtesy and etiquette norms are for puzzle setting, but I feel the need to warn that there are a couple quite long hypotheticals required to reach the solution, about 5 steps long if I had to say.
