In ".NET MAUI Blazor Hybrid and Web App"-type project, got "An unhandled error has occurred" in GUI but to error output anywhere

ARTICLE AD BOX

I have created the project of type ".NET MAUI Blazor Hybrid and Web App" type and made some manipulations. It is no matter what exactly I have done for this question because here we are talking about absence of the clues in .NET MAUI / Blazor output, not about that something wrong in my code. So, I will not say what exactly I have done because - the target is to know from the some kind of output.

When I starting the Windows version of the application, I got the "An unhandled error has occurred" message:

enter image description here

An unhandled error has occurred. Reload 🗙

There are no any errors in the browser developer tools (yes, the browser developer tools may be launched even for Windows native application - I suppose because .NET MAUI uses the web view):

enter image description here

There also no clues about errors in Debug output:
