    So i got this problem since early october mayby mid September.
    Im on windows 10, ASUS TUF A17 (FA706QR) , bought in July.

    Right now the symptoms are pointing towards MediaTek Wi-Fi 6 MT7921 Wireless LAN.
    As i come across many have bsods with this card and drivers.

    Here is what i did so far:

    "Changed the security privileges for directory Machinekeys" (i cant find the post)
    "You can also set a Firewall rule to Allow c:\Windows\System32\taskhostw.exe to the internet." from early post in this thread.

    The Scep error dissapeared but bsods and random crashes and restarts continued.

    I noticed on crashes:
    Crashes when going out of energy saving, or logging in after screensaver activates.
    Internet randomly stops/disconnect and 15-30 seconds later computer freezes and eventually restarts.

    Trying diffrent mediatek drivers, no luck.
    Seems better now, i inactivated any energysaving when plugged in, havnt had a crash in +24 hours now.
    (saturday crashed once or twice per hour)

    So is there many of you out there with Mediatek wifi adapters experience same problem in this context?

    (Right now im on driver 2021-07-30 3.0.1.1185)

    I have been experiencing the same issues as everyone else in this thread, on Win 10, ASROCK mobo, Ryzen 5 chip etc.

    Everything was working fine prior to enabling fTPM in the BIOS. Now the machine crashes within 5 mins of boot.

    Yesterday in desperation I shifted to the insider Beta channel and upgraded to Win 11.
    The error is no longer output to the log, however crashing is still frequent, with the machine failing to successfully dump any errors when it crashes now.

    My only hope at this point is for the machine to be stable long enough to install the dev release, and hope like hell that this fixes my problems. Will update here if this proves to be the solution.

    If anyone has any suggestions please let me know

    Given the situation, is there any reason I shouldn't go to 11?

    I have this error too. In my case sometimes when I'm playing a game the screen freezes but the sound continues, after 2 to 5 seconds the screen goes black and the computer restarts by itself. This is very rare to happen, but it only started to happen after I went to the BIOS and activated FTPM. Another problem that came up was a random stutter where the mouse and the audio start to stutter for like 3 or 4 seconds and then everything goes back to normal. This happens at least once a day, sometimes twice a week and can happen either by playing a game, watching a video or listening to music. There's a video that shows exactly what happens, here's the link: https://youtu.be/NntnoKWlOEA

    I've done a lot of research and I'm not the only one to have these issues that span several Ryzen CPU generations with FTPM enabled, as well as different motherboard chipsets like the B350, B450, X470, B550 and X570. I don't want to risk updating my motherboard BIOS without being sure it will fix these issues, as many have already updated but for them it didn't fixed the issues with FTPM... Also because the latest BIOS version available for my motherboard is still in beta version.

    So I ask, could these issues be related to this SCEP AIK Certificate error?

    Gigabyte B450 Aorus M
    BIOS F50 (AGESA 1.0.0.4 B)
    Ryzen 5 3600
    EVGA GTX 1660 SUPER SC 6GB
    16GB RAM (2x8) 3600Mhz
    Windows 10/11 Home

    Evidently this issue has been resolved with the latest Dev-Build update (yesterday, Monday, Nov 15, 2021). I run Insider Editions therefore I cannot validate since I'm generally several days behind the Dev-Build OS updates. None-the-less, I wanted to share this information. The individual who posted did not indicate what the Dev-Build number is. Be patient is all I can say.
