Any advance in debug? On my side, I am working on magick.
On some around 50ko image, in browser a pop-up displays:
timeout -k 40.0 20 magick gif:/tmp/RackMultipart20250927-23598-xrrp6e.gif -auto-orient -background white -interlace none -flatten -debug all -quality 90 jpg:/tmp/image20250927-23598-9ujq3d.jpg and no image is loaded
If bigger size, no pop-up but loading wheel is turning in loop infinitely with no result. No error is logged in /var/www/discourse/log.
