Stuff breaks all the time, you just need a bigger sample size.
Overseeing IT admins for corp fleets is part of my gig, and from my experience, we get malfunctioning TPMs on anything consumer - Lenovo, Dell, HP, whatever. I think the incidence is some fraction of a percent, but get a few thousand devices and the chance of eventually experiencing it is high, very high. I can't imagine a vTPM being perfect either, since there isn't a hypervisor out there someone hasn't screwed up a VM on.
Many, many more devices here... And good/typical enterprise level hardware... And failing TPMs are just something that happen. It's pretty expected these days. And on Windows when it causes a loss of certificates, it's actually a good bit more of a pain than just a dying disk or display or something, because it's not immediately obvious what's wrong, it just doesn't talk to the network properly anymore, or so.
I'm not surprised by Tailscale's change here. It's a good move.
The issue could be a bug in the host OS not in the VM. I had a Windows update that broke VMs when the guest OS was Windows running in real-time mode. This was the only issue and if I didn't run real-time VMs I would have never known. The only resolution was to reinstall Windows.
