Hi Olivier,

Please try some suggestions bellow to see if the problem can be resolved:

1. Update or Reinstall Drivers
   • Update your graphics card drivers via Device Manager or the manufacturer’s website.
   • If using Intel hardware, consider uninstalling the Intel ME driver if it is causing conflicts, as it is not critical for gaming.
2. Repair or Reinstall Minecraft Launcher
   • Delete the .minecraft folder in your user directory (back up saves first).
   • Reinstall the launcher from the official Minecraft website.
   • Run the launcher as Administrator to ensure proper permissions.
3. Check Java Installation
   • Ensure you have the latest Java Runtime Environment installed if using Minecraft Java Edition.
   • Remove older or conflicting Java versions to prevent access violations.
4. Close Background Applications
   • Terminate unnecessary programs in Task Manager that may interfere with Minecraft, such as overlays, antivirus scans, or other resource-heavy apps.
5. Adjust System Settings
   • Disable Vulkan or OpenGL conflicts if the launcher crashes due to graphics API changes.
   • Ensure Windows is fully updated and system files are intact using sfc /scannow in Command Prompt (Run as administrator).
6. Alternative Launchers
   • If the official launcher continues to fail, using CurseForge or other modded launchers can sometimes bypass the error, though not all modpacks may work.

If you have further information, please feel free to let me know.

Hello,

please download and install the latest graphics driver from your computer manufacturer’s website.

If the issue continues, please check the Windows Event Viewer and share any crash logs related to the Minecraft Launcher.
