After multiple crashes on open (& subsequent discovery/deletion of corrupt error log), restart of laptop, new crash on open/attempt to index after download of updated resources, Logos is open & is now REBUILDING the index (my command; it thought the index was "done"). Hopefully this will correct the issue.
After discovering the log file was corrupt, I deleted all the old logs. All the new logs are attached.
