I get these errors when I launch the game through the Gaijin.net updater, the app running at start.
When I create a link to aces.exe on my desktop, and give it admin rights, the game launches with Easy anticheat instead, and then I can launch the game.
That’s why I started with verify integrity.
If you have Steam that’s done through game properties.
You can start manual launcher and verify game files there as well.
