  • Re-enable mods one at a time and test the game after each to identify the mod causing the issue.
  • Once identified, check for updates for that mod or seek support from the mod’s creator for compatibility issues.

4. Run Baldur Gate 3 As Administrator

Running Baldur’s Gate 3 and the Script Extender with administrative privileges can resolve permission issues that might be preventing the Script Extender from working correctly.

5. Temporarily Disable Firewall And Antivirus

Sometimes, antivirus software or firewalls can mistakenly identify the Script Extender as a threat and block it from working.

Temporarily disabling these programs can help determine if they are the cause of the problem.

For Firewall:

  • Click on the Start Menu and open the Control Panel.
  • Select ‘System and Security’.
  • Click on ‘Windows Defender Firewall’.
  • In the left sidebar, click on ‘Turn Windows Defender Firewall on or off’.
  • Choose ‘Turn off Windows Defender Firewall’ for both private and public network settings. Be cautious with this step, as it will leave your computer more vulnerable.

  • Select the time frame for which you want to disable the antivirus if prompted. Choose the smallest time frame possible, as you’ll want to re-enable protection as soon as you’re done testing.
  • After disabling, try running the Script Extender to see if the issue is resolved.
