The first time I ran the cells the program was fine, then I started using FindRootPlot, but it didn't work well so I removed the line and went back to using FindRoot and it gave me some crawl errors that I don't quite understand This is the program working well

This is the same program but after I used the FindRootPlot

I think the recursion behavior is due to the use of Subscript(See 77625).

To solve this problem:

  1. Stop using subscripts for evaluations.
  2. Use Clear["Subscript", "x"] to clean the definitions(which are cleaned by your Quit).
