User and Permissions Management Issues in Microsoft Entra ID (Assigned Roles)

try these:

Force Sync from Device: Try restarting the device to see if the permissions update takes effect.
Intune Sync: If you're using Microsoft Intune, initiate a sync from Intune to push the updated policy to the device.

Go to Microsoft Endpoint Manager Admin Center > Devices > Select the affected device > Sync.

Manual Update: Run the following command on the device to force policy updates:
gpupdate /force

If permissions are still not updated, clear cached credentials

Run dsregcmd /leave to disconnect the device from Entra ID.
Rejoin the device using dsregcmd /join

Ensure that you are running PowerShell with elevated permissions (Run as Administrator) when using dsregcmd /join

Check Task scheduler for any errors in related tasks
