Looks like this is a instance of microsoft/msquic#4132. On OSX, We're using MsQuic at this commit: microsoft/msquic@e0385b0 build from main (therefore having version of the next release - 2.4).
Historically, the above mentioned issue had a fix by that time: microsoft/msquic#4145
Unfortunately, the were at least 2 follow ups it seems:
Which are not part of the binaries with which we're testing.
Also this is likely the reason for all the other timeouts and hangs on OSX.
TL;DR This should get fixed by new MsQuic, i.e. with #114912
Alternatively, we can change the async cert validation condition to
