One of the Gutenberg blocks that I was using was causing the WordPress White Screen of Death when I tried to make a new Post or Page. After disabling every add-on one by one the Ghostkit block was the problem, which is a pity as I used it to display a lot of images in earlier posts and to also add a border to some items. So till I find a suitable replacement there are some Posts that will be displaying images with an incorrect size and/or style.
