Windows 10 update - effect on Photo Gallery

I've used Photo Gallery from Live Essentials (2012 I believe) and its predeccesor for years as my basic photo viewer and editor.
Recently, and I think its since the 1909 update, it's not opening large JEPG files (30-50 MB in size).
Additionally it's taking an age for a full folder of many images to open and display the contents in thumbnail view.
Photo Gallery is, IMHO, one of the best basic viewer editors ever. Have M/soft disabled it in some way? If so is there any way of getting it back? I have PS Elements and PS6 but for ease and speed of use Photo Gallery is (or was) so good.

But there's a difference between not being supported and being positively disabled. Winmail, an excellent email client beloved by many, had a crack enabling it to be used for years after it became unsupported, then 'disabled' (unless you knew about the crack) then finally disabled for good.

I use Movie Maker from Windows Live Essentials 2012, but I have to have Photo Gallery as it gets installed along with Movie Maker. I use Movie Maker regularly, but for photos I use the even older Paintshop Pro 7. But I've just tested Photo Gallery and that works fine too. Although Windows Live Essentials is long out of support, it still seems to work.

It's quite difficult to find a jpeg that large, so I had to make one by enlarging and saving at highest quality. I'm on the latest update for 1909, build 18363.657.

These were copies of Tiffs and PSD files - which really can be enormous!

How did you convert them to jpeg? It may be something in the conversion from TIFF to JPEG that Photo Gallery doesn't like. How is it at opening other JPEGs, say from your camera?

Not sure now precisely how they were converted - long time ago. But the point is that these were openable without delay until one or other of the more recent updates of Windows. And there's a point. The last update to 1909 would not take place normally on this PC. I ended up reinstalling a fresh version of Windows using the media creation tool - after a couple of frustrating hours trying to figure out why it wasn't happening automatically. I can't be sure but I suspect that might be when difficulties with Photo Gallery started.
