Multiplayer is not dead. You can find lobbies in the evening time. Only TDM. We save the legacy of this game.
No bug / problem from my side, it works normal.

It kept crashing on startup until I pulled a big-brain workaround: booted into Windows Safe Mode, launched the game, switched it to windowed mode, then rebooted back into normal mode. Worth noting, getting into Safe Mode on Windows 11 is an needlessly complicated process, which made the whole thing exceedingly annoying. But I guess Activision couldn't possibly spare half a day's work of a single dev to fix this in the last decade, when they have all those AI-generated skins to work on.

Even after all that, the game still crashed a couple levels in, and continued to crash every time I tried to load that level.

At that point, I gave up. Not worth the hassle, especially when the original runs just fine on Xbox via backwards compatibility. You're basically paying fifty bucks for a broken mess just to get some shinier (but already dated) graphics, when you could be playing the original and saving that money for something much more pleasant, like a day at the spa or a Cornetto.

I'll be taking my refund now, thank you.

The game repeatedly crashed, preventing me from finishing the campaign. I searched online for solutions and found thousands of reported issues related to this game. Therefore, I've decided to request a refund. One moment, it would work fine, and the next, it would stop functioning altogether.
