Images refusing to display for some addresses

After the latest update a couple of months ago, various email addresses weren’t showing images. So I did the obvious, and simply allowed images for the affected addresses. But some addresses simply no longer display images at all. I have tried all of the settings options, including download images from untrusted sources, and set images to always download, and have even tried instructing it to download unsafe content from all senders. But for a very few addresses, there is no luck, and I have unreadable emails. I can access them just fine on my phone. The problem is with Version 9.2.2307 Windows 11 (I don’t have a licence for Version 10, and don’t intend to upgrade)
