Secure boot updates cannot be applied - SBAT error 0x800700c1

[Robi69]

Hello.

I have a Notebook HP Spectre x360 with BIOS AMI F38 (8.12.22), Intel Core i7-8705G CPU @ 3.10GHz and Radeon RX VEGA M GL Graphics card,  and Windows 11 pro (24H2)

Since one of the last driver updates from HP (over Windows update) and Intel (over Intel driver and support assistant) i have 2 Windows errors in event viewer with Secure Boot:

1 Secure Boot certificates have been updated but are not yet applied to the device firmware. Review the published guidance to complete the update and ensure full protection. See screen 1

2 The Secure Boot update failed to update SBAT with error Unknown HResult Error code: 0x800700c1. See screen 2

I hope someone can help me to solve the problem. The NB have the latest updates of all drivers who was available.

I tried following:
1. reinstalled the BIOS F38
2. disable legacy boot
3. deleted the secure boot keys in BIOS
4. switched back to secure boot
5. take care that Trusted module in Windows is showing and active

But the failure is not gone and i cannot boot in secure mode.
