Hello,
The Sports widget is definitely not deprecated like Maps, so this is likely a service sync failure or a corrupt package. Since you're on a ThinkPad, are you signed into the Widgets board with a personal Microsoft Account or a Work/School account?
Work accounts can sometimes hit provisioning errors with consumer widgets on specific builds.
Also, are you running any VPNs, strict firewall rules, or DNS sinkholes (like Pi-hole/NextDNS) that might be blocking the specific API call to pin the widget?
Finally, when you said you fully reset widgets, did that involve running a PowerShell command to remove the Windows Web Experience Pack like @Anthony Lee suggested, or just restarting the processes and signing out?
This distinction matters for the next step.
