What is NBA 2K21 EFEAB30C error code?

Like most NBA 2K errors, error code EFEAB30C has no official definition from the game developer. However, in many cases where it’s been observed, it looks as though it’s part of a larger group of bugs for this NBA 2K21 that is triggered when the game client is out of date.

What are the causes for error code EFEAB30C on NBA 2K21?

There’s been a number of possible reasons that we’ve compiled that might be the ones causing this error code. Let’s discuss each of them briefly below.

Closing MyCareer and going back to the main menu will allow the download and installation of the update. Afterwards, the game should be back to normal.

Corrupted game files.

In some cases, damaged game files may falsely trigger an error code. If NBA 2K21 game is already updated but you continue to get this error, there may be a problem with your local files.
