Dear list,

Since the 20191029 update I have not been able to create a document via
MKIV, suffering from the subject error message (error, no format found
with name: cont-en, aborting).

I have tried cache clearing, regeneration, and complete fresh installs.
None work. I suspect it is something on my system, but cannot think of a
relevant change except possibly a Win10-64 system update.

Attached is the log from the latest install try (with filenames of
copied files removed).

LMTX has no problems.

All suggestions welcome.
