ed-scout: Crash on startup when attempting to open chrome UI

Reported by fenland_idiot:

Hi JonCage, Im interstered in using ED-Scout but it keeps erroring out / not starting. This is my latest log file: 2020-08-22T18:32:22.407Z - EDScoutWebUI-EDScout - INFO - ED Scout v1.2.4 Starting 2020-08-22T18:32:22.762Z - EDScoutWebUI-EDScout - INFO - Found existing Scout instance PID:7524, killing off before continuing 2020-08-22T18:32:22.784Z - EDScoutWebUI-EDScout - INFO - No HUD overrides file detected (C:\Users\Ben\AppData\Local\Frontier Developments\Elite Dangerous\Options\Graphics\GraphicsConfigurationOverride.xml)

Any Ideas? I do have a job load of other ED plugs, such as Dr Kai’s profile launcher, EDDiscovery and ED Market connector, but I still get a crash with none of those launched?
