Players are advised to restart the game and remove the door icon map marker to prevent the error, at least until the software update arrives.
Metroid Dread has proven incredibly popular in its first week, becoming the UK's best launch in the series to date.
However, MercurySteam has addressed criticism that they left out workers from the credits of the game, stating the company's official policy requires developers to have stayed at the studio for 25% or more of a project's development time.
