Ok it looks like that particular gateway was set to be the Default application in settings. Could you try something for me? Open the Designer launcher and when you see the auto-launching screen select Cancel on the bottom. You will then see a screen similar to the one that I posted. Click on the manage button on the thee-dots button to the right of the name of the Ignition-LAPTOP-RLSQD170 Designer: 
Delete the application. After doing this, re-add it by click the blue “Add Designer” button and attempt to launch again.
Thanks,
