Send me the file and I will look at it. As mentioned, a picture is a
description but it's not code. Happy to help and check if we have
something to work with.
It would be helpful to know platform, and lilypond version.
I know in these sort of cases often MWE"s make it hard to duplicate the
issue, so the whole file by mail would allow me to check it. I have seen
this before when people do voicing in idiosyncratic ways that are not
syntactically wrong but can cause issues.

Here's a picture of the last line so far:

You'll see the correct output in the second beat of bar 92. Also
notice that in bar 91 there is a chord of five notes of which the top
stem points up, the bottom stems down. When I copied this into bar 95
I got the same error, so I had to put all notes into the same voice.
How can I find out what's causing this error?
