Nautilus (gnome file manager) doesn't show thumbnail previews of images and videos

Recently shifted to Cachyos from Windows, but thumbnail preview of video/images not generating on the GNOME default file manager, Nautilus,

Enabled every option from preferences, installed ffmpeg-thumbnailer but no help

If I set no preview, then the orange colour image shows as preview (default), otherwise everything is black

tried with upgrade the package also from flatpak, didn't work either

Kde file manager dolphin shows preview thumbnail perfectly, so plz help me to fix this issue

Start by reviewing the linked CachyOS log and reproducing the missing image and video thumbnails in Nautilus with previews enabled. Compare the behavior with Dolphin, then identify the Nautilus thumbnail-generation failure indicated by the report. Done means Nautilus displays thumbnails for the affected images and videos without relying on the orange placeholder.
