(reliably) crashes on Android 8 when fetching/containing images

I use K9mail on multiple devices since eternity. Since the latest update it crashes on an old Galaxy S10 / Android 8 when fetching images (show remote images) or, it looks like, when the message has images. It crashes on 80% of mails with image. I can provide you with messages that reliably crash (e.g. newspaper newsletter from nzz.ch) and with only one that works (newspaper newsletter from 20minutes.ch) Plain text and plain HTML text messages seem to work fine. it works fine on all other [android 12+] devices Re-install the current version did not help re-installing an older version from FDROID worked Help is apprechiated
