Biset leads to:
commit d723b90344c0e56b26fc69aa00cb3001e074a723
Author: Jean-Marc Lasgouttes
Date: Mon Sep 6 14:52:42 2021 +0200
Break multi-row strings in one pass
Replace FontMetrics::breakAt, which returned the next break point,
with FontMetrics::breakString, which returns a vector of break points.
To this end, an additional parameter gives the available width for
next rows.
Rename various variables and methods accordingly. Factor the code in
breakString_helper to be more manageable.
Adapt Row::Element::splitAt to return a bool on sucess and provide
remaining row elements in a vector. The width noted above has been
added as parameters.
Rename the helper function splitFrom to moveElements and rewrite the
code to be more efficient.
Remove type of row element INVALID, which is not needed anymore.
The code in TextMetrics::breakParagraph is now much simpler.
In Row::finalize, remove the code that computed inconditionnally the
current element size, and make sure that this width will be computed
in all code paths of Row::Element::splitAt.

The problem here is that the placeholder is not replaced before being used.
In order to see what python is being used you can see:
Help->About LyX
In a hunch does the attached patch fixes the issue?
The idea is to replace the placeholder when the converter is added/imported.

If you go step by step in gdb you'll see that last steps before the exceptions
are:
lyx::TextMetrics::redoParagraph:522 pm.rows() = breakParagraph(bigrow); -> step

LyX has caught an exception, it will now attempt to save all unsaved documents
and exit.

I do not know enough about row structure to inspect what's wrong with the
variables.

Hi Jose,
this what I see in curent master:
1. start lyx
2. load file
3. this is what I see in terminal window:
env: '$${python}': No such file or directory
Most likely related to image preview conversions, this what I see with debug
messages on graphics:
graphics/PreviewLoader.cpp (757): PreviewLoader::finishedInProgress(127):

These binaries available on my system:

BTW Update::Force is defined as '2' and the hex value of 4294967293 is FFFD.
