Sample error:

I suspect this is quite common -- it looks to be majority of the build failed "unknown" errors (~1000) in Crater results (https://crater-reports.s3.amazonaws.com/beta-1.61-1/index.html).

I suspect this is due to #94373, so we'll probably want to verify that and revert at least for 1.61 (pending further investigation). But mostly suspecting just due to it being an obvious TLS-related change in 1.61 (could also be #92123, but seems pretty unlikely).

I verified it bisected to #94373 (cc @erikdesjardins).

Assigning priority since the comments indicate that it could affect many crates (Wg-prioritization Zulip thread)

@rustbot label -I-prioritize +P-high

Since we reverted the PR (across beta and master) I'll go ahead and close.
