Details:

It seems to be a tradition, new version of biblatex recently updated on CTAN
crashes tex4ht configuration. This time it produces several error messages and
doesn't produce any citations nor references.

One problem is that some macros introduced in 3.0 were removed again, so we
probably need to make test for minor version and leave them in biblatex 3.4.
The other problem is that biblatex does some things in \AtEndPreamble{}
command and we can't fix it easily. It tries to redefine \MakeUppercase and
\MakeLowercase macros, but patching fails, because they are redefined by
tex4ht as well. The other thing is that it process list of babel languages and
loads language files for them (it is probably requested only in some
bibliography styles, for example Biblatex ISO 690 [1]). For some reason, the
language files are loaded correctly, but code which should be executed only in
case of failed loading is started. This results in run time error and language
handling doesn't work.

I've modified biblatex.4ht to fix these issues, but it needs more testing, in
particular with previous biblatex version, if someone has access to it.
