Game freezes on startup before PS/Bungie logos

Second time encountering this issue.  The pattern seems to be:
1. Play a session without any issue earlier in the day
2. Attempt to play again later in the day (~2ish hours from the last session in this case)
Bug: Game freezes on launch before the ps/bungie logos.  The Steam overlay pop-up in the lower-right that usually goes away after a few seconds remains there, leading me to think the game has completely crashed at this point. 

Saw a similar issue in https://help.marathonthegame.com/hc/en-us/community/posts/50788783126292-My-game-keeps-freezing-on-launch-before-the-sign-in-screen so I ran through the advice given there: ESC key does nothing.  No corrupt files in Steam file verification, no overlays active, restart did not resolve the issue, drivers are up to date and I don't have another network to test with (not even sure what you mean by this, get another ISP?  I release/renewed my IP, no effect.)
