I have quite a few machines with UEFICA2023Error 2147952750 (even some in High Confidence buckets), from different manufacturers (Lenovo, HP, even Hyper-V virtual machines on a Windows Server). Others have a 2147946825, or 2147942405. What am I expected to do with that error code? UEFICA2023Status is blocked to "InProgress", AvailableUpdates does not make any progress.
