.elementor .elementor-widget:not(.elementor-widget-text-editor) figure {
margin: 0 ;
}

breaks various image and portfolio plugins as it is a pretty specific selector, overriding their image margins. You cannot double up on the not arguments so you'll have to come up with a solution otherwise or just drop this declaration altogether, what was it fixing ?

For example, visual portfolio uses

.vp-portfolio__item-wrap .vp-portfolio__item {
    margin-left: 40px;
    margin-top: 40px;
}

to put a margin between masonry elements. If you add their gallery to elementor using the shortcode box, the images come out with no spacing due to your css blanket.

Somebody tried to report this months ago but their bug-report was super vague and so it got closed.
