Avast causes the new Forza Horizon 5 game to crash to the desktop

Playing new just released Forza Horizon 5 and Avast silently is causing the game to lockup and crash to the desktop, disabling the antivirus temporarily fixes the issue and it never crashes again until the antivirus it enabled.

I’m running Avast Premium Security 21.8.2487 (build 21.8.6586.697), running on Windows 11 Pro 21H1 build 22000.282

Hopefully this can get looked into as this game and antivirus are not playing nicely together whatsoever.

Update to the latest version (21.9): https://forum.avast.com/index.php?topic=306968.0

Hello, last assembly (21.9.2494 (assembly 21.9.6698.561)) Everything has such a problem.

Hello

this is probably caused by the game anti-cheat engine. Can you please try to make AV exclusion for the game folder? It is installed in folder
C:\Program Files\WindowsApps\Microsoft.624F8B84B80_3.405.2.0_x64__8wekyb3d8bbwe

Unfortunately not working

Can we have a fix for this… exclusions do not work only uninstalling works for my instance

Any updates on this?

The gaming forums are on fire.

I tried adding the exception as suggested above, but this didn’t work.

Steam forums are now suggesting to just completely uninstall Avast, because the game works if you do this.

Edit: I’m on Avast version 21.9.2494 (build 21.9.6698.561)

Updated to the latest Avast version and added an exception the the entire Windows app folder, still crashes. Thankfully the game does work flawlessly for hours at a time when Avast is disabled but that’s unacceptable for an antivirus.

Seems Avast had a similar issue a few years back with FH3 that was Avasts fault once again.

Avast premuim user here. Unless it’s uninstalled, FH5 crashes on startup.

I can also confirm that Avast is causing the game to crash. Ive tried as suggested to update Avast to the latest version and to make a exclusion of the games folder. This doesnt fix it and the only way to fix it for me is to uninstall Avast. I hope you can fix this issue fast as it is making me consider cancelling my premium subscription and seeking a alternative anti-virus

Hello,

can somebody (afflicted user ) provide a Process Monitor log (.pml file) of such failed game execution?

Only filtered log for FH5 execution. Sorry that unfiltered one is over 9.8 Gigabyte.

Thank you very much gawainrol. I can see that werfault.exe was executed right before process termination, which means that crash dump was probably generated in c:\ProgramData\Microsoft\Windows\WER, can you please check the folder and provide the crash dump?

I did, look

Thank you doom2004, unfortunately these are only crash report files, not crash dumps.
For those of you affected: can you please also provide Avast support package: https://support.avast.com/en-us/article/Submit-support-file/

Only reports in WER.

What about Microsoft Store version of the game, can you please confirm issues with Avast installed, or is it Steam version only?

Thank you

I have steam

Same problem with the Microsoft Store edition…

Confirmed. I am using the Microsoft Store version - same problem as Steam with CTD.
