Hi folks, We just upgraded our umbraco instance from 11.5 to 12.3.7, and now the thumbnails for previewing media in the media library is now not working. Fun fact, is that thumbnails for .SVG files are perfectly visible, while jpg, png and so on, is showed with the defult "jpg" fallback image. When opening the console, i can under the network tab see that the images for .svg files are fetched, but nothing else is. I have tried and checked the data that is returned from umbraco to the media page, and there are no difference between svg's and jpg, other than the name and the file extension. So for me it is not obvious what the error is. Thanks in advance
