I'm getting Error 5 and and 1796 TPM-WMI Error.
"The Bluetooth driver expected an HCI event with a certain size but did not receive it.
The Secure Boot update failed"
I'm getting multiple error 5. Can anyone look at the log and help?
Also getting a TPM-WMI 1796 error (pasted under first log)
Trying to hunt down a random crashes
I have done a Windows update reinstall, no love
Please and thank you in advance!

I would examine this and the part labeled "Take Action" in step 1 and step 3.

TPM is a hardware part designed for security tasks. Error 1796 often points to issues with TPM firmware or WMI communication, which may involve problems during TPM setup, firmware, or settings.

Thank you for your message. I've been using this setup for seven years, and the problem appeared even after no hardware modifications. Could you clarify how it should be fixed?
