Hey @EA_Leeuw You're right to assume I've already tried that. Other than Steam, I've reinstalled everything else at least 10 times. I've also tried everything under the EAC's troubleshooting page at least a dozen times.
As I said, I can get BF2042 to run about 80% of the time after moving it to my system drive. However, when I quit the game, it freezes Steam and Origin ThinClient. If I try to kill them from the task manager, I get a "you're not authorised to do this" message. This suggests it's EAC's doing, considering neither Origin nor Steam runs with kernel-level privilege and can't prevent Windows from killing them.
You can google "lost ark eac 10110" or "battlefield EAC 10110" and see the other people who're experiencing this issue.
