I cannot reproduce the reported issue, but that may be because
unauthenticated access doesn't work for me, regardless of the
setting of ::allowUnauthenticatedAccess; I get an
Sabre\DAV\Exception\NotAuthenticated either way.

What am I missing?

Hi,
I tried with 7.3.20 (x86) and 7.4.8 (x64) and could still reproduce the issue.
I made the zip file available at https://mynebula.net/index.php/s/pf8XMciDxEHeqXD

Are you still experiencing this issue with PHP 7.3.20?  If so,
could you please make the files available again?

Thanks for the switft reply.
Afaics, php-cgi.exe does not actually crash. Otherwise I would expect a trace of that in the windows
event log. But nothing is logged there. Neither is there anything in the PHP error log.

Is it possible to actually get a backtrace if a process doesn't crash but simply exits? If so,
how do I do it then?

What I do have is a function trace from xdebug. 
See https://mynebula.net/index.php/s/F6QAZwYdLK5MaNx

Btw, is there a way to attach files to this bug report?
