It seems that line plot does not support row names for the Y matrix which start with numbers. This is acceptable but there should be a clear error message...
Error in tidyr::pivot_longer():
! Problem while evaluating all_of(mn_xy).
Caused by error in all_of():
! Can't subset elements that don't exist.
✖ Elements X1X, X2X, and X3X don't exist.
Run rlang::last_error() to see where the error occurred.
