#1 . First, you need to find Archive Block ID.
In my example, it is: #block-yui_3_17_2_1_1724993380134_6825

#2 . Use this code to Custom CSS box

#block-yui_3_17_2_1_1724993380134_6825 ul.archive-item-list {
    min-width: 500px !important;
}
#block-yui_3_17_2_1_1724993380134_6825 .archive-group {
    overflow: visible !important;
}
