This is a weird one and hopefully I've properly distilled the MWE.  Here's
what I think is happening:

If you have a parenthesized crescendo with a spanner style of none, when
the line breaks, it creates two small parentheses under the new line and
throws two programming errors.  Here's the MWE:

\version "2.25.13"

music = \relative {
  c''4 c c c | \break
  c4 c c c |
}

dynamics = {
  \override DynamicTextSpanner.style = #'none
  s2. s4\parenthesize\cresc |
  s4 s2.\! |
}

<<
  \new Staff \music
  \new Dynamics \dynamics
>>

The output looks like this:
