This same problem started happening for me this morning, too. In my case, though, the listed ftdibus.sys driver file is oem130.inf.
I was in touch with microsoft support during a couple of hours to address this. They tried different things such as scan for integrity.
In the end, they advised to do an in place upgrade of windows 11.
I was reluctant to do this, and indeed for a while my computer looked really broken. I had to do again a series of windows update until apps and microsoft store work again.
Bottom line is however that the memory integrity can still not be activated.
Again due to ftdibus.sys.
But this time the published name has changed: oem30.inf (import date: today).
I will go to bed now. Hopefully tomorrow is more sucessful.
