@kisak-valve I found the issue, I did a bios up date, resetting TPM, Tailscale seems to have a bug causing it to spin trying to setup the network devices, IMHO this is still a steam bug, as it's not gracefully handling a network change, a private network interface that Steam isn't even using. Shouldn't permanently leave broke half downloaded files in the cache.
Nothing extracted yet.

Please describe your issue in as much detail as possible:
Steam seems to work fine in Firefox
Cache misses seem to periodically fail to load resources from the internet:
