Welcome to the forum. FYI Hiding a monthly cumulative after uninstalling it won't stop the code within the cumulative that broke your onedrive from coming back. It will be part of the next month's cumulative (unless MS acknowledges there is a problem and fixes it before then). IMO pausing updates would be a better solution until there is a fix.

It is deprecated. That's why it's not longer listed for download, and you have to "know" the legacy URL.
But it still works.

I agree, rolling back and stopping updates is a stopgap measure. MS will either fix the issue in a future update, or release a newer OneDrive client. The latter is probably easier for MS since they don't have to wait for the next scheduled update.
