Error creating XAML completion metadata about avalonia HOT 3 OPEN

I had the same issue. But my project compile is working very well.
I am trying to figure out what is wrong with my project settings, but I can't find the problem.

This is a known issue.

You can fix it by uninstalling the newest version of Avalonia for Visual Studio Extension and installing the previous version of the extension.

Worked for me!

I had the same issue but my Avalonia version was 11.0.10.
I guess the reason behind it is that there is no references file in the folder obj/Debug/net8.0/Avalonia. Since I had several local Avalonia projects, I just found an Avalonia project which worked well regarding autocomplete and then copied the references file from it to the one which did not work well...It worked for me.
