Game blocked by Windows 11 Smart App Control

Hello everyone, I hope you are all doing well!

Since earlier today, Windows 11 Smart App Control is blocking Warhammer 40k Battlesector, which is strange since I've played the game for nearly 20 hours in the past couple of weeks. The message in the screenshot says that this is happening because GameAssembly.dll have no digital signatures (the attached image is in Portuguese, sorry about that).

Anyways, I believe that disabling the Smart App Control would fix this for anyone having the same problem, but that doesn't seem like a real fix. I'm not sure why this is happening now and I didn't found anyone else with this issue when searching around. I would just like to let the devs know about this and hope that it gets properly fixed in the future.

Thank you and kind regards.

Thanks for the report. We've seen this in some other Unity games too. Looks like it might be change in W11, but we will have to work out why! In terms of it not working even with the app control disabled, it might have deleted or quarantined the DLL entirely. You could try reinstalling the game to see if that fixes it.

Cheers
