Mac: OneDrive Couldn't Start: Please restart your computer and try again
I'm actively dealing with the same issue. This started right around Sep 10th or so.
I think I found a solve but you might not like it: READ THIS ALL BEFORE TRYING IT
Use Activity Monitor to close our of all OneDrive stuff. Navigate to One Drive in your finder window, right click and show package contents, click Contents, click Resources. Then I opened the RemoveOneDriveCreds.command then I ran the ResetOneDriveApp Standalone.command scripts.
Warning: this looks like it does remove / delete the sync completely. So the OneDrive folder will disappear from your finder window. If you've been using your OneDrive folders even while you've had this syncing issue, I'm fairly certain you will lose these unsynced files. BACK UP YOUR STUFF. Anything you worked on while OneDrive has been failing you'll probably lose.
I just went through this process. It removed all the OneDrive folders from my machine but OneDrive is running now. I went onto OneDrive.com and set the folders to sync and they're now downloading onto my computer again.
Followed the steps above, thanks ! I recommend to NOT use the
button, but instead at Shared Libraries to your OneDrive by
adding a shortcut to OneDrive. This way the folders will sync as well (also always keep on the device) but is more reliable.

My issue is that I need to refine those 30 shares to bring back. Additionally, that's going to blow up timemachine on me.
As a work around, I need to test it but I was able to extract out that OneDrive has an 'odopen' URL scheme. I've written a script to extract what URLS are registered and I think have a way via CLI to restore them back.
Depending on how this works, I may end up publishing a github repo with scripts one can use to save a 'config' of OneDrive sync's one has. In the event you changed laptops or lost them, be able to restore those syncs without having to rediscover them all over again.- DanielTDSSep 16, 2026Copper Contributor
Check out my reply.
The update to the insider preview restores all accounts that were working up until the problematic version.I have 4 accounts and various custom sync'd SharePoint folders etc. All work after the update to insider version 26.163.0823.0004
