I have found that I can no longer view, export and batch convert into a WebP format since around 1.8.0 64bit MP
The changelog for this version (which i am having and installing as a .deb file on Debian 11) shows LibWebP 1.4.0 - https://www.xnview.com/mantisbt/view.php?id=3300
Help / About / Plugins shows libwebp.so
ls -A1 /opt/XnView/Plugins|grep webp

Other image viewer view/export webp fine. (XNViewMP did too, but in previous versions)
What to do please?
