Hi @Kamal ,
You can have a check if the UpgradedEvent handler prevents the upgrade action. And you may uninstall the old version then install the new one. If it does not get work, we suggest you raise a ticket in the Office 365 admin centre, the backend group could troubleshoot it with Correlation ID and help you further.
Best Regards,
Baker Kong
