Is the issue reproducible without mods?

Yes. I have looked in my ArmA 3 Steam folder, and removed any mods there. It happens with and without mods. I have validated my files several times and reinstalled the game three times now. I have also updated my graphics card's drivers. No change.

Here is a screenshot if it helps: https://gyazo.com/f20a30511821696ab8a486381267cd2b

I also have tried switching to and from dev branch, deleting my excess player profiles and deleting my MPMission cache. No change.

Can you please try running your steam as admin?

I tried that with no result, did the same with the launcher. I did get the game to work from running the game's client itself with admin, but I'd have to reset the game whenever I tried to join a server because it wouldn't activate BattleEye. Mods still worked with it, servers still ran fine. I would really like to be able to use my A3 Launcher tool so that I can load mods more easily.

I get the same error if I try and run the game without admin or attempt to run the game from the launcher

Any new info?

This issue is most likely caused by mismatch of data. Could you try verifying your game cahce?

I verified my cache and now when I launch the game it gives me a blue screen which I can alt tab out of. Waited for 10+ minutes and the game never did anything.

Do you have anything for me
