Status Update:

While investigating this bug, I filed PulseAudio bug 75418.
https://bugs.freedesktop.org/show_bug.cgi?id=75418
It might be related or involve a similar fix, but it is not the cause
of this bug because the Windows X2Go Client does not set
XDG_CONFIG_HOME for the pulseaudio.exe process.

PulseAudio bug 75006 is also worth noting:
https://bugs.freedesktop.org/show_bug.cgi?id=75006
Currently, the Windows X2Go Client does not set PULSE_COOKIE. It
instead sets overrides USERPROFILE and expects the cookie to be
created relative to it.
