Hi there,
I'm sorry to hear you're running into the 0xC0000409 error.
Since you've already tried those steps, let's check a few other possible causes:
- Perform a clean boot
- Repair or reinstall the Microsoft Visual C++ Redistributables
- Check for any pending Windows updates
- Update your device drivers
- Use the System File Checker tool to repair missing or corrupted system files
- Confirm that you’re using an Administrator account on your PC. If you aren’t, you can configure a new administrator account. Then, reinstall EA Javelin anticheat/the game
- Locate and delete the CryptBase.dll file from the game installation folder if it is present, then clear the Steam download cache.
- Disable the Wi-Fi adapter and leave only the Ethernet connection enabled
If the issue persists, could you please share your DxDiag report? Also, was the game working previously, and did this error start after a recent update?
Thanks for your patience!
