There's a packaging error in ucode, where a fresh install contains the old ucode from the original 24.10.2 image creation, but the newer ucode-mod-uloop has had its ABI changed...
Just upgrade the ucode and libucode packages to 2025.07.* and it should start working again. I strongly recommend that you do an immediate owut upgrade after the ucode upgrade to make sure that all of the ucode-mod-* are updated to a consistent set.
$ owut check
