8.9.1 to 8.9.2 upgrade trashes the site
drush up - performs the 8.9.2 upgrade but completely replaces the "vendor" directory - deleting existing needed 3rd party config directories and overwrites composer.json completely also breaking the site.
Status report will not load and Commerce config page are both broken to a 500 error "not working" page - in part because the upgrade deleted the commerce stripe libraries in the vendor directory among what would be other things
On the D7 site - still running thank god - this same command works fine
Copying the /root/drushbackup files back to the location brings the old site back up
Not good
Postponed: needs info
