Hi,
To know the issue more clearly, would you please confirm the following questions?
1, Was the issue on the specific PC or all the PCs?
2,Did the issue happened every time when there are updates?
3, I would recommend you check more details about the group policy by the GPSVC LOG
For more information , you can refer to the following link:
