The attached is a Wikipedia of figured bass. Almost all features can be exported into Musicxml for braille transcription, good! But there are two places where the continuation lines are incomplete, perhaps because there are multiple lines. At bar 48, there's only a "stop" tag given; and at 66, only two "continue" tags are given. I think every line should go into its own figure.

For reasons as of yet unknown, the attached file displays in my MuseScore 3.5 (on MacOS) without either the light gray duration lines or the black continuation lines. This makes debugging quite painful. This issue seems specific for this file, other files display OK.
I also found it's strange that the code shows only continuation value of the two lines, one with stop only, very strange. Probably this issue is just for this work, for when I input a line, it converts ok in xml. So this may be the problem of the file, not the conversion.
Issues understood.
First of all, the invisible light gray duration lines and black continuation lines are caused by the duration of the figured bass elements being zero. I suspect this is generated by older MuseScore version, but am not sure yet.
Second, the incomplete continuation lines are generated from incomplete figured bass figures (containing only an underscore). These are found on the D2 in measure 48 and on the F2, G2 and Ab2 in measure 66. The exporter does not expect these and consequently handles them incorrectly.
