Das hat ein Techniker von GrandRP mir geschrieben. Ich probiere das die Tage mal aus und gebe Bescheid, obs geklappt hat.
Here are a couple of ways to fix it.
Option 1:
1. Go to the folder with RAGE:MP run it as an administrator.
2. Without closing the folder, connect to the server.
3. At the time of the connection, run as an administrator EACLauncher.exe (It is in the folder with RAGE:MP)
4. If that doesn't work, try it 2-3 times.
Option 2:
1. As soon as the blue EAC download bar reaches the end, start RAGE again.
2. Wait for the game to start.
3. Exit the game.
4. Open the Task Manager.
5. Find the process called Easy Anti-cheat Service (EOS).
6. Remove the task and try to log in again.
Option 3:
1. Go to the folder with GTA V.
2. Uninstall gta5.exe, run playgtav.exe as administrator, do a full file check.
3. Go to the folder with RAGE:MP.
4. Delete ragemp_v, config.xml, multiplayer.dll, multiplayerL.dll.
5. Run updater.exe as administrator, click on the desired server, wait for the download and installation.
Option 4:
1. Remove game mods that hook into game code - rage:mp will whitelist them ASAP, so at the moment you cannot use ReShade, ENB and the others.
2. Verify OS integrity - Use the System File Checker tool to repair missing or corrupted system files
If you have issue ”application is unable to start correctly”
Install these DLLs:
The Visual C++ Redistributable Packages install run-time components that are required to run C++ applications that are built by using Visual Studio 2013. For an updated version of these redistributable packages, see KB 3138367.
http://www.microsoft.com
A security issue has been identified leading to a vulnerability in MFC applications that are built with Visual Studio 2010 and ship the Microsoft Visual C++ 2010 Service Pack 1 Redistributable Package.

Also disable Windows Deffender, it sometimes blocks access to this file.
If you have issue "Easy Anti-Cheat is not installed"
Install any other game that has easy anticheat, such as Steam - Brawlhalla
Epic Games - Fortnite
If you have windows lower than 10 then update it

Alles getestet. Funktioniert nicht. Es liegt einfach am Server. Hab langjährige Spieler gefragt und alle meinten, dass man damit leben muss. Eigentlich schade für so einen „großen“ Server mit mehr als 1k Spielern am Tag. Weil ich mein nach einem Crash, muss man schon echt sehr motiviert und gefangen sein wieder drauf zu joinen und zum Ort zu fahren, wo man gecrasht ist.
