WPF DataGrid last column width set "*" not work

Question

I have a DataGrid with 4 Columns in total, the first three columns are Auto in width and the last column is Star, but I don't know what changes were made and now the last column has become very narrow in width, I used VS hot reload, removed Star and set it again and the column width is normal, I guess the DataGrid has not gotten the correct width when rendering.
