This particular error generally means that some strange issue has occurred with your character which is causing troubles when trying to play. Character errors in particular can cause issues when loading the game as your character is essential to functioning in the game at all. To address this particular error, there are a few steps to follow which are described below.
Try Again Later
Probably the simplest troubleshooting step, sometimes this error can resolve on its own, as the servers catch up and properly process your character and account data. Step away and come back after about 10-15 minutes have passed and try again.
Complete a Character Repair
For anything related to character-specific data, this step is essential for attempting to correct it. The Character Repair function tells the servers to reconstruct the data for your character avatar, which can resolve certain issues like this error. Our dedicated Character Repair article goes over all of the important points about what this will do, and what it will not do.
Remember that after initiating this, it may take some time to complete. Try logging in again after about 10-15 minutes to ensure that the process is not interrupted.
Check for 3rd-Party Application Conflicts
When data is transferring over the Internet, sometimes seemingly helpful programs designed to protect your computer or make your online experience smoother and more pleasant simply cause more problems. Anti-virus, anti-malware, and anti-scripting programs can prevent data from transferring properly due to seeing it as potentially harmful or risky. VPNs (Virtual Private Networks) that route through locations with intermittent connection issues can also cause troubles that can potentially cause data corruption.
We do not recommend totally disabling your security and privacy programs to resolve this error, but it is possible to whitelist certain programs, files, and apps within some of them. In this case, you will want to whitelist the game files (generally, the .exe files) for both the RSI Launcher as well as Star Citizen itself and check if that has resolved the error.
Alternately, for things like VPN services, especially those VPNs that come with additional anti-malware features like NordVPN and ProtonVPN, temporarily disable them and try logging in to see if things resolve.
If the above steps do not work...
In the event that all other troubleshooting steps fail, then the next step is to gather information about your experience with this error and post on the Issue Council. Important details are what you were doing last in game before this error appeared and troubleshooting steps already attempted. If you manage to resolve the issue, it is also good to add your account anyway along with what worked to fix it as that can help narrow down the cause.
