dotnet 8 sdk downloading failed

### Describe the bug.

When I open an avalonia project, it occurs.
I have seen several same issues, but I don't think the problem is solved in plugin 2.0.2. As you can see, error happened again.
I'm pretty sure the internet connection is ok, The plugin installed .net 7 successfully before install .net 8.
