In Libreoffice writer (6.4.7.2), when I insert an image (not using copy paste, but the insert menu) it appears properly. Then strangely when I save it immediately disappears. Other images I have inserted remain, but the latest image disappears. This has happened to me before with other largish documents (15MB). Libreoffice has also been crashing particularly often lately.
I have tried the same image as both .jpg and .png files, as well as other images, and the same problem re-occurs. Strangely, when I insert the image onto a different page, there is no problem.
Any ideas?
(Btw. this is from Ubuntu 2020.04 LTS)

Thanks for the quick response. I have upgraded and it has solved the problem. Best wishes.
