Some file names are random numbers now and some logs full with errors appear.

Some of my animations are called ER9qn.webm previosly it always was the name that you downloaded from the store (Sometimes animation changer breaks for me so i delete it. Once i could keep the animation not anymore know i have to copy them over and there filename is random). Within desktop mode if you go to .steam > root > logs I have logs that have constant errors and they disappear if I delete animation changer.

Animations are supposed to be downloaded as <ID>.webm based on the SteamDeckRepo ID. As far as logs are concerned, the plugin does have an issue on the plugin store version, which could explain log errors, but should be fixed in the testing store.
