Can't load new model "file not found"

I installed this:
https://nmkd.itch.io/t2i-gui
v.1.12

It works with the included in installation model. When I try to put my .safetensor ot to download with the GUI model from huggingface, it is visible in the GUI, but when I start image generation, it opens Error message:

Model "model file name" file not found.
It is renamed, moved or deleted.

So can't works with different models.
