Please provide the following when posting an issue:

original .tex code

\begin{myenv}
  yo it's your boy here kwshi back at it with yet another example to break latexindent
\end{myenv}
it's been a good couple months hasn't it how you been my friend i've been starting to miss you having not been on here filing issues for so long that i was so excited when latexindent started acting up again, gives me a good excuse to come chat with you

yaml settings (taken roughly from https://latexindentpl.readthedocs.io/en/latest/sec-the-m-switch.html#lst-tw-bf-myenv-yaml)

modifyLineBreaks:
  textWrapOptions:
    columns: 60
    when: "after"
    blocksFollow:
      other: |
        (?x)
        \\begin\{myenv\}
        |
        \\end\{myenv\}

actual/given output

\begin{myenv}
	yo it's your boy here kwshi back at it with yet another
	example to break latexindent
\end{myenv}
it's been a good couple months hasn't it how you

desired or expected output

\begin{myenv}
	yo it's your boy here kwshi back at it with yet another
	example to break latexindent

Issue doesn't occur using when: before. Curiously enough the issue with extra indentation also doesn't occur within the environment (after \begin{myenv}); it also goes away if I introduce an extra blank line after \end{myenv}, or a blank comment (which is an OK workaround).

Probably related to #450 and #412.

Also, an observation that may come in handy for troubleshooting: the extra indentation lines up exactly with where the \end{...} line ends. See this other example:

\begin{myfriendhowareyou}
	yo it's your boy here kwshi back at it with yet another
	example to break latexindent
\end{myfriendhowareyou}
it's been a good couple months
                       hasn't it how you been my friend
                       i've been starting to miss you
                       having not been on here filing
                       issues for so long that i was so
                       excited when latexindent started
                       acting up again, gives me a good
                       excuse to come chat with you

and notice how hasn't it how you ... is indented to exactly where {...areyou} ends two lines above it.

Apologies for the delay, I'm hoping to get to this soon

Thanks for this.

As of 38cf7c3 if we start with

defaultIndent: "    "
modifyLineBreaks:
  textWrapOptions:
    columns: 60
    when: "after"
    blocksFollow:
      other: |
        (?x)
        \\begin\{myenv\}
        |
        \\end\{myenv\}

then we receive

\begin{myenv}
    yo it's your boy here kwshi back at it with yet another
    example to break latexindent
\end{myenv}
it's been a good couple months hasn't it how you been my
friend i've been starting to miss you having not been on
here filing issues for so long that i was so excited when
latexindent started acting up again, gives me a good excuse
to come chat with you

I'll get this released soon. Thanks again.
