So, let me close this ticket.

As of 2024-11-18, my hypothesis is:

there are some sort of race conditions between PC/SC + card reader (or its driver) + smartcard + scdaemon on Windows, at least at initial use after boot
because of this, SCardConnect of PC/SC call wrongly fails (somehow confirmed by @ebo's experiments + @gniibe's speculation), or wrongly never returns (@gniibe's guess, side info: its slowness is observed in T7400).
