I had a Ryzen 3900x on a gigabyte motherboard and the fTPM was just totally unreliable for a pretty mainstream combination. Not fully sure which was to blame there.

At least it was fixed in the 5900x (and _different_ gigabyte motherboard, but from the same lineup) that replaced it.

This jumped out to me because I had a TPM problem on an FM2 Gigabyte mobo in ~2015. (Back when a TPM on desktop mobos required a plug-in module.)

It took me months of hassling Gigabyte to get them to issue me a beta BIOS that fixed the bug, and the fix never did make it to a non-beta BIOS.
