I tried this and worked for me
THANKS !!!
I've spent many hours on a new PC (W11 Pro, 23H2 22631.3085) trying to resolve this very issue - having read many sites and tried solutions that DID NOT WORK.
sachin.kr's solution WORKED !!
!
I went from the "standard hardware security not supported” message to fully restored.
Interesting that important step in the above fix was greyed out on the problem computer but not on the one that doesn't need fixing.
Corrupt files on top of corrupt updates and dysfunctional software.
