My friend has tried all the solutions and nothing. I can only assume this is a Microsoft Store issue (wouldn't surprise me) of some kind and Paradox talking with them or checking their Game Pass distribution would be required to fix it for all users.

If messing with anti-virus or changing store location fixed it for you, luckyyy.

Just chiming in to add my experience. The game worked fine for me when it was first released months ago. In the time since then is when the "Antimalware Service Executable" started seeming to go nuts and CKIII would fail to open the launcher.

I did get it working via turning off Real-time protection, but tried a bunch of other stuff from around the 'net first. It's possible it was a combination of Real-time protection and one of these other measures:
  • Create exception rules for/disable Windows Defender firewall & ransomware protection
  • Create exception rules for/disable third-party antivirus (was only using Malwarebytes - I simply disabled it)
  • Uninstall and reinstall the game
  • Sign your Microsoft account out of the Xbox app and add it again
  • Create a shortcut to the game and "run as administrator"
  • Delete a number of files related to the Paradox launcher and CKIII game from AppData:
    • C:\Users\<username>\AppData\Roaming\Paradox Interactive\launcher-v2
    • C:\Users\<username>\AppData\Local\Paradox Interactive\launcherpath
    • C:\Users\<username>\AppData\Local\Paradox Interactive\launcher-v2
  • Delete a number of files from C:\Users\<username>\Documents\Paradox Interactive\Crusader Kings III:
    • .launcher-cache
    • dlc_load.json
    • game_data.json
    • mods_registry.json
  • Launch the game through the Microsoft Store instead
  • "Repair" and/or "Reset" the app through the "Advanced Options" on the CKIII entry in the Add/Remove Programs interface
I do use a non-standard installation location for my Xbox app - it is configured to install games to my X drive. I do wonder if that could be some factor in all this.

CKIII's real install path on my system is X:\WindowsApps\ParadoxInteractive.ProjectTitus_1.0.96.0_x64__zfnrdv2de78ny, which is hardlinked to by C:\Program Files\WindowsApps\ParadoxInteractive.ProjectTitus_1.0.96.0_x64__zfnrdv2de78ny . I tried every File, Folder, and Process exclusion I could think of to try an exclude the files and binaries in both directories from Windows Security's measures, but as others have detailed the exclusions had no effect - only disabling real-time protection.

As a final note, my system does seem to experience the issue detailed here on Microsoft Answers, where every 10 seconds an event detailing some sort of Activation permissions error related to the Xbox app is recorded. answers (dot) microsoft (dot) com/en-us/xbox/forum/xba_wowpc-xba_gowxb/xbox-beta-app-creating-system-logs-every-10-secs/30c060e3-3a89-4f7c-acf2-306c28e168e8

(Right click cpatch.exe, choose properties, switch to compatibility tab.)

When I try to run after that, I get this exception:

But after I hit OK the launcher comes up!

Um, this works.
Yeah this works, so something is going on with cpatch not having necessary permissions to read/write to the disk.
All the jazz about anti-virus stuff and such doesn't do anything.
So to do this, here are the steps:
Go to your Windows Apps folder (typically located in C:\Program Files\WindowsApps)
If it asks for permission to access, you'll need to right click the folder, go to the security tab, click "Advanced", then change the PRINCIPAL at the top (put in your windows username)
Apply, then close the window.
If it didn't ask you or you have set up access from the steps above, go to ParadoxInteractive.ProjectTitus_1.0.96.0_x64__zfnrdv2de78ny within the Windows Apps folder.
Then go to launcher ---> bin
When you see cpatch.exe, right click it then go to Properties
Then once that's open, go to Compatibility
Check "Run this program as an administrator" then click Apply.
Click Ok.
Then try launching Crusader Kings 3.
The error that taconium got will appear, just click ok.
Play as normal.

Glad this worked for you as well. (And nice job elaborating on how to actually get access to WindowsApps. I didn't even think to mention it.)

Note with this fix, mods don't work at all.
Even manually throwing them into the mod folder does nothing.

On the bright side, the game works fine.
