"When I want to watch my gameplay, I notice an error message says This replay file has been corrupted and couldn’t be loaded. How to fix this problem?" Developers, content creators, and coaches heavily relied on the replay files for analysis and content creation. However, they may encounter a bug that corrupts replay files after matches. This article explains why this problem happens and how to fix it with effective solutions.

Part 1: Why Replay File Is Corrupted

The replay files in League of Legends are recordings of your gameplay. It allows you to review your matches, analyze strategies, and learn from practices and mistakes. These files are saved locally on your hard disk, but you can only access them through the League of Legends client due to encryption. Why do you encounter the error that this replay file has been corrupted and cannot be launched?

1. File transfer issues. Transferring replay files from one folder to another, especially during the downloading process, can corrupt League of Legends replay files.

2. Improper shutdown. If your gameplay suddenly crashes or your computer unexpectedly powers off while a replay file is being saved, it may become corrupted.

3. Outdated game version. You’d better keep your game up to date; otherwise, you may encounter compatibility issues with replay files.

4. Software conflicts. League of Legends records your gameplay and saves the replay file in the background. If other software running in the background interferes with the LOL client, a corrupt reply file error will occur.

5. Converting the replay file to MP4. League of Legends encrypts replay files and saves them in ROFL. If you convert them to MP4, the LOL client cannot recognize them.
