Help with backend Please !

[SilverBolts]

Hello, i installed Swarm on my machine and everything was good. I ran out of disk space so i moved the swarm folder from one drive to the other. the main Stable Diffusion v1.5 model worked, but i installed wan2.1 model recently and it says the error 'No backends available!'. I updated the paths for ModelRoot, clip, and diffusion_models/unet and still no backends. the models are in the folder models/diffusion_models. Thanks for the help

Here's some console lines that might help :
