Picard 2.7.1 downloaded using update prompt from earlier version (2.6.??).  User settings retained during upgrade.

Picard crashes with "Picard terminated unexpectedly" window.  Uninstalling/reinstalling Picard and removing user settings does not change behaviour.  Log file follows.

(I previously had a mapped network drive X, but it has never been used for installations, source files, rips, or anything else to do with Picard.)
