I’m getting a similar error. From doing some research, KERNELBASE.dll is not the perpetrator, that’s just the unfortunate victim. The perpetrator is obviously your <Game>Server.exe.
In order to properly find the root cause of your issue, I highly recommend you copy over <Game>Server.exe along with the .pbd which will contain the symbols and stack traces for what wrong.
Personally, I got the error when trying to use FModuleManager::LoadChecked to load the GameLiftServerSDK plugin that I added to my Plugins directory. I have seen other threads with similar error messages. This could be a stackoverflow or just improper importing of a library that doesn’t exist. I am wondering if your case is similar. This could also be improperly built dlls or libs
Some solutions that have worked for other users is simply deleting the packaged contents and repackaging the editor, server.
I’m still looking for a fix. I’m intending on posting here if I find a solution to my error.
