[wasm][7.0] Blazor Wasm debugger not working anymore

### Is there an existing issue for this?

- [X] I have searched the existing issues

### Describe the bug

When I try to debug my Blazor Wasm application (cs files), I got stucked with debugger. Debugger not hit and I got some wierd error on visual studio and in console. I didn't find any resolution during my research last 5 days.
I need help ASAP because we really cannot accept situations like this, We are big fan of Blazor and .NET stack but unfortunatelly if we do not solve this issue we cannot continue our projects in this technology, it is not acceptable to have issues like this.

It worked before but now there is no chance to make it work again. I didn't change anything in my code base but windows updates, visual studio update.

I did re-installed all SDK-s, re-installed visual studio, even check .NET core 8 preview, but without success.

It is important to mention that i'm using authentication, (OpenIdDict).
.NET 7, VS 17.6.2

### Expected Behavior

Expecting to have working debbuger breakpoints inside razor.cs files.

### Steps To Reproduce

### Exceptions (if any)
