VS2022 debuger crashes when reading HTTP Response Object response.Content.ReadAsStringAsync();

[nssidhu]

I am using VS2022 preview 3.1 with Blazor WebAssembly Hosted Project.

I have code where the Debugger crashes and have to start over Debugging again.

in my client side(WebAssembly Project) i have the following code inside trycatch whcih runs into error.
jsonString = await response.Content.ReadAsStringAsync();
The control does not execute the catch block, it simply crashes.

Here is the response from API call from the Newtwork tab of browser.

I noticed in your screen recording that the debug console included the line Failed to resolve member access for jObject[ReturnDataParameterName].ToString()

Maybe a long shot, but could the Watches you have added be causing this behaviour? Try removing those and see if it makes any difference? Still would not expect the debugger to crash, but it might send us in the right direction.

Removed those from watch window, still the same problem.

@nssidhu thanks for contacting us.

@lewing this looks like something in the debugger proxy is failing
