I have a Asus TPM on an ausus motherboard.
Everything was ok until i cleared my TPM on build 19613 (i am on 19628 and issue is still present.
After clearing the TPM nothing that uses a TPM works (thank god i didn't have bit locker on) for example WhFB PINs and Face IDs cannot be registered.
Installing a clean 1903 build resolves this issues.
I note on fast ring builds all TPMs i have (Dell XP13, surface book and this asus mobo) all are reported as having different security flaws and need a fw update - there are no updates (or rather i am fully upto date on public ones). Is the build flagging
a set of undisclosed security flaws - or is this a bug?
Is the team aware of a bug that once a TPM is cleared this builds are no longer able to initialize and use it (and yes I have tried all the command line tools to reset and initialize).
This is the output of tpmtool.
