DEBUGGING IS NOT ENABLED for new Blazor WASM project in Chromium.

Is there an existing issue for this?

• I have searched the existing issues

Describe the bug

I have created a new Blazor Hosted WASM app using Visual Studio for Mac 17.6 Preview (17.6 build 983).
Debugging in visual Studio is working fine; breakpoints in both the server-side and client-side are being hit properly.
I have confirmed that we are using the "Development" environment.
When running the app, I get the Blazor error, "An unhandled error has occurred." yellow bar.
When I view the javascript console to see the error, I see blazor.webassembly.js:1 DEBUGGING IS NOT ENABLED.
This happens both when debugging in Edge and Chrome.

Expected Behavior

Browser debugging should be working in Chromium browsers.

Steps To Reproduce

1. Create a new Blazor Hosted WASM project
2. Run debug in Visual Studio
3. Open Developer tools in Chrome
4. Click the Mobile icon to switch to mobile viewing
5. Select iPhone 12 Pro and refresh app
6. Blazor error bar will appear (this is a bug too but will open a separate report)
7. Click into javascript console
8. See, "DEBUGGING IS NOT ENABLED"

I'm sorry, I don't fully understand, when you run the app using VS you said that:
"Debugging in visual Studio is working fine", so you can pause on breakpoints that are in Counter.razor file?

Then you want to debug using the browser and not the VS, did I understand correctly?
If this is the case you should start the app outside VS using dotnet run.
Launch the browser that you want and navigate to the URL.
Then Press Shift+Cmd+D, this will open Developer tools or tell you instructions about how to launch the browser to get debugging enabled.

I am having the exact same issue, as soon as you put the browser into F12 mode and select say iPhone 12 Pro, the error occurs. Driving me crazy.
