JavaScript error ，After closing the new window

[sFireFrog]

Electron.NET CLI and API ：11.5.1
.NET Version：.net 5.0
Node.js Version: 14.16.0

• Target: win

I already have the main window and create a new window. If I close the new window and then call up the development tool, an error will be reported.

Steps to Reproduce:

1. Create a main window during initialization
2. Use a button to create a new window
3. Close the new window to call up the development tool
4. If there is a jump page in the main window, an error will be reported every time you jump

I am seeing this as well, but I'm seeing it when I reload the main window after closing the second window.

You can do this by setting Closable=false on the BrowserWindowOptions.
