Cause
The issue is rooted in Microsoft's One Drive configuration. Our team has submitted an issue at Microsoft Graph SDK to bring it to Microsoft's attention. In addition, a rework EXTPLESK-6197 is planned to update the msgraph-sdk-php library version in Plesk to address this issue from our side.
Resolution
Workaround: Temporarily reconfigure Plesk to create backups on some other storage (local or remote). That can be done via Tools & Settings > Backup Manager > Schedule or via Websites & Domains > example.com > Backup & Restore > Schedule menus.
