You need to contact the developers and ask them what the issue is since they have access to the source code and can tell you

Hi,

I’ve installed the Harmonic Pattern Scanner on cTrader Desktop (demo account, latest version). When I click the “Settings” button, I get a blank white window. After enabling WebView2 and installing .NET 6 runtime, I now get a system error:

System.NullReferenceException: Object reference not set to an instance of an object.
  at Syncfusion.Windows.Forms.MetroForm.UpdateSystemButtonsImages()
 

System.NullReferenceException: Object reference not set to an instance of an object.   at Syncfusion.Windows.Forms.MetroForm.UpdateSystemButtonsImages()

I’ve tried all the following:

Reinstalling the bot

Launching cTrader as administrator

Ensuring full access permissions

Installing all required runtimes

Nothing resolved the issue. The bot UI fails to render.

Please advise if this is a known bug or if an updated version is available.

Thank you!

This is a programming/coding issue. The error message makes it apparent - the code is trying to use an object that isn't being initialized or set in the code, hence the “null reference exception”.

The coder of the bot needs to debug their code and find out what it is.

Or they can share the code with someone to help out.

Either way, from everything you've shared right now, it's a pure coding issue, and nothing to do with cTrader itself.
