Team Fortress 2 doesnt launch anymore after updating my arch install

I updated my Arch install a few hours ago and I cant launch Team fortress 2 since then.
Things I've tried:

Verify game data
Reboot
Reinstall Steam
Deleting Steam folder

Things I haven't tried yet:

Reinstall Arch

Any other game seems to work without any problems

Many people have mentioned using llvm16 broke compatibility, rolling it back or moving to Flatpak Steam will make the game run again.

- rolling it back
  
  How would I do that?

  I'm not sure sadly, I don't use Arch. I would expect there's a way of uninstalling llvm16 and re-installing llvm15. Again, if you don't need the hassle you can just use Flatpak steam for these games.

  WDYM? It is compiler, nothing should change only because changed it's version and did nothing else.

  They made breaking changes in the newest version and many programs that rely on it aren't working.

Roll back to before the update

- do I look like I have backups?

It's because of llvm v16. It has been discussed on reddit a few monts ago, see this.

- Should I just downgrade llvm?

  Downgrading might fix it but it can also create dependency issues for other packages, you could try it but I would recommend you first try flatpak version of steam. Don't know if it will work but it's better to try that one before downgrading a package.

src/tcmalloc.cc:278] Attempt to free invalid pointer 0x9f3dad0

Bug in Valve code? Not sure, I'll test on my system.

- Mine just works. We can compare packages in our systems.
  
  EDIT: I found this post, it seems problem lies in tcmalloc. If you have tcmalloc in your system, then you can try to disable one shipped with TF2.

Try to use the flatpak version of Steam to see if its some library that has been updated what's causing TF2 to not launch.

It happened to me with CSGO and haven't found a fix for it yet so I have two versions of Steam now.

- This is one thing I really like about Flatpak, never having to worry about missing or broken dependencies. Totally worth the bigger install size imo.
  
  One thing to note if you go this route OP: If you use Steam Input, you’ll also need to install the steam-devices package (game-devices-udev on Arch), or setup udev rules manually. Flatpak still doesn’t let apps do this automatically as far as I’m aware, but it’s smooth sailing aside from that.

  Please read logs in post. There is no mention of library problem.

Pop! OS.

  Use a stable, non rolling release operating system.
