Cyberpunk 2077 won't launch after updates

I was able to play the game with no notable issues on 2025-02-18. I did not try launching it again until shortly before this post. When I attempted to launch the game, Heroic notified me that there was a pending game update; I allowed it to run and install it. Upon clicking the green Play Now button, after a few seconds a small window opens and immediately closes, and the Play Now button shows up again. I've already ensured that my flatpak is up to date using the command listed in the FAQ. I also previously tried launching the game under Wine-GE-Proton8-26 and GE-Proton9-22, with no noticeable difference.

have you tried forcing an update if available and/or verifying the game files?

this looks odd, try reinstalling heroic with the command from this message https://discord.com/channels/812703221789097985/1044301598018515105/1044301598018515105

I tried running flatpak update && flatpak install --reinstall com.heroicgameslauncher.hgl again, but saw no changes. The new game log is identical, apart from time stamps.

I uninstalled/reinstalled the game, and it now works normally. I remembered that I selected an alternative EXE to skip the RED launcher. Perhaps that had something to do with the issue? I know that people on slower (sometimes metered) connections will be hesitant to redownload an ~80 GiB game. Since the root cause wasn't identified, I'll let the team decide whether or not to tag this as solved. For posterity, here's the error from the end of the game log:
