I have never had a bike do that, even a folding bike with short stays for 20" wheel.
Clicks a little, not super smooth, but never jump, even fully crossed.

Check rear end alignment, chain line etc. If you have a square taper BB, you can go shorter, but not the hollow, external bearing stuff. You can remount the chainrings inboard with spacers. 46t ring would buy you about one cog shift in the rear. Make sure rear D has enough capacity, and front D can adjust inwards enough. Pop on a different wheel or cassette for test.

Assuming clean 10s chain, lubed, of good quality, normal spring tension, minimal wear on anything etc.
