Adobe recently auto-updated as of 8/23/23. I generally need to edit PDFs by adding text, then occasionally adding an image. I add the needed text as normal, but when I insert an image, it allows me to select the image from My Computer as normal, and then nothing happens. There is no error message, the dialog box for image selection simply disappears.

If I close the PDF and re-open it, and go straight to adding an image first, it loads into the PDF and I can place/resize/move it as usual with no issue.
