Riot has officially acknowledged the “Critical Error” bug and is working on a solution.
Bugs and League of Legends go hand in hand. Almost every patch introduces new client or in-game issues, and Patch 13.7 is no exception. A game-breaking bug was introduced with the patch. The bug in question is the system “Critical Error” bug.
What the bug does is it causes the player-side client to crash. This can happen at any point during the game, from the beginning to the middle; it happens randomly. The game may also crash many times throughout a game or, in certain situations, each time the game is launched. Crashes like these happen occasionally and are easily remedied by restarting the client; however, the bug crashes not just the client but also the System. So, effectively, the only method to resume the game is to restart the PC.
A game-breaking issue like this is unacceptable in any game, let alone one as popular as League of Legends. Players also share the sentiment and ask Riot to fix the bug quickly.
In response, Riot has issued an apology to players and stated that they are “working hard to get it fixed.” They also shared some fixes that should mitigate the issues.
How to Fix the “Critical Error” Issue
Here are some of the potential fixes for the issue in League of Legends,
- Set LoLClient.exe properties in Windows: “disable Full-screen optimizations.”
- Set the LoLClient.exe properties in Windows: “Run as Administrator.”
- In the League client, click the settings icon -> General -> Set Close client during the game to ALWAYS.
- In the League client, click the settings icon -> Game -> select “Prefer DX9 Legacy Mode.”
Following these steps should likely fix the crashing problems, but if it doesn’t, you might have to wait for Riot to officially fix the issue later down the line.
