Close VALORANT and Riot Client, restart Windows, and note whether an error includes a VAL or VAN code. Use Riot's exact code page when it does. Without a code, update Windows and the official graphics driver, close conflicting background apps with a clean-boot test, and repair or reinstall the game only after the simpler checks fail.
Before you continue
CodeUse the exact VAL or VAN solution when shown.
UpdateInstall Windows and official graphics updates.
Open Settings > Windows Update, install available normal updates, and restart if required.
4
Update the official graphics driver
Install the driver from Windows Update or the PC or graphics-device manufacturer. Avoid a third-party driver updater.
5
Run a clean-boot comparison
Use Riot's launch troubleshooting to temporarily reduce background startup conflicts, then launch VALORANT once. Restore normal startup afterward so the PC is not left in a diagnostic state.
6
Repair or reinstall only after the comparison
If the failure remains, follow Riot's current repair or reinstall path for VALORANT and Vanguard. Keep screenshots and settings until the game opens successfully.
7
Collect logs when it still fails
Use the Riot Repair Tool instructions, attach the resulting log archive to a support request, and include the exact time and last visible screen.
If the game opens during a clean boot, restore startup items in small groups until the conflicting app is identified. Do not leave security software disabled.
If the error says Windows cannot access a file, make sure VALORANT is not forced to Run as administrator in Compatibility settings before reinstalling.
If launch fails after a graphics update, use the device manufacturer's supported rollback or reinstall option rather than changing random GPU preference files.
