Issue: How to fix "A critical error has occurred" Valorant error on Windows?

I can't open Valorant because I keep receiving the “System error – A critical error has occurred and the process must be terminated” message. Please help me fix this since I'm unable to play Valorant at all due to this as of recently.

Solved Answer

Valorant, developed and published by Riot Games, has established itself as one of the premier first-person shooter games in the gaming community. Known for its tactical gameplay and vibrant graphics, Valorant offers a competitive environment for players around the world. However, despite its widespread popularity and acclaim, players often encounter technical issues that can disrupt their gaming experience. One such notable problem is the “A critical error has occurred” error message, which presents a significant inconvenience for many players.

The “A critical error has occurred” error typically manifests with the full message, “System error – A critical error has occurred and the process must be terminated.” It can occur at varying points during gameplay, abruptly forcing the game to shut down, much to the frustration of players. In more severe cases, this error prevents Valorant from launching altogether, effectively barring players from accessing the game. There are even instances where this error leads to a Blue Screen of Death (BSOD), signaling a more serious issue within the system.

The root causes of the “A critical error has occurred” in Valorant can be diverse. One common factor could be outdated or corrupt drivers, especially those related to your graphics card. Drivers are crucial for the smooth functioning of games, and any mismatch or corruption can lead to such errors. Another potential cause might be conflicts with security software.

Antivirus programs, in their effort to protect the system, can sometimes mistakenly identify game files as threats, leading to such critical errors. Additionally, issues related to full-screen optimization and compatibility settings in Windows can also trigger this error. These settings, while intended to enhance gaming performance, can sometimes backfire, resulting in unexpected shutdowns or crashes.

Access geo-restricted video content with a VPN

Private Internet Access is a VPN that can prevent your Internet Service Provider, the government, and third-parties from tracking your online and allow you to stay completely anonymous. The software provides dedicated servers for torrenting and streaming, ensuring optimal performance and not slowing you down.

Don’t pay ransomware authors – use alternative data recovery options

Malware attacks, particularly ransomware, are by far the biggest danger to your pictures, videos, work, or school files. Since cybercriminals use a robust encryption algorithm to lock data, it can no longer be used until a ransom in bitcoin is paid. Instead of paying hackers, you should first try to use alternative recovery methods that could help you to retrieve at least some portion of the lost data. Otherwise, you could also lose your money, along with the files. One of the best tools that could restore at least some of the encrypted files –  Data Recovery Pro.
