The main cause is damaged files in the Data folder or .idx files, but problems can also be caused by broken cache, network issues, or antivirus programs getting in the way. In this article, we will discuss different ways to solve this error.

Keep in mind, COD: Modern Warfare is a large game. Uninstalling and re-downloading it can take a lot of time—especially if your internet connection is slow or limited.
