Yes, accessing Google Drive Backups works now, but unfortunately the last available backup in my Google Drive Backups in Tabs Outliner is from 3 weeks after I last managed to make a backup. So I still can't recover all my work from the last 3 years, since I don't think the admin stores older backups and he's gone rogue.
Thank you EliiO, it actually worked! I can open old backups now. Unfortunately, I'm 3 weeks late, since the last available backup in my Google Drive Backups in Tabs Outliner is from 3 weeks after I last managed to make a backup. I assume the admin saves the user backups on a server somewhere and deletes the files that are older than 3 weeks. The admin has gone rogue, so it seems like I'm out of luck. Thanks anyway!

Please! Can someone help me find out where old backups are stored!? I'm willing to pay an award for the recovery of any of my old backups from before Feb 20, 2020. The last one I have before this network error occurred is from 2016. So I've lost everything from the past 4 years, and my work will fire me if I don't get it back. I'm really freaking out and desperate.
