The developers have not announced the release date of the fix yet
Following the release of the version 1.05 patch for MultiVersus, Player First Games announced on Twitter that they were temporarily disabling access to the LeBron James character in this game due to a critical bug. The developers promised to report on the timing of the release of the fix separately.
LeBron was removed from the playable character list shortly after the update's release. Some players have noted that a bug that occurred when using this fighter caused his special attack to deal damage to the opponent, regardless of their distance. Performing this technique, LeBron did not release the ball from his hands either during or after the strike, which did not impose a de-buff effect on him.
While you wait for the return of the second highest-scoring player in the NBA, you can try out the new MultiVersus mode or experience the latest roster expansion Black Adam, voiced by industry veteran Bob Carter. You can find the latest patch notes here.
