Dear developers,

I am using ConTeXt LMTX version 2020.09.05 21:18 on Windows 46bit.

I have a large project for which I can reproduce an access violation:
    mtx-context     | fatal error: return code: -1073741819
Unfortunately, the error vanishes as soon as I alter any detail in the
project's source code.

The access violation happens always at the same location. I have produced a
log file for which I have enabled \tracingall just before the error
happens. I suspect that the error is triggered due to tagging information
written to the PDF (\setuptagging[state=start]), because disabling tagging
prevents the error. The log file (as a ZIP archive) is here
<https://drive.google.com/file/d/1xv5ZxQi4IfyS50HD60z-Nk-FOW_-afU-/view?usp=sharing>.
Does this help or do you really need a MWE?

Kind regards
Christoph
