My Entity Is Invisible, and I Don't Know Why

In my mod, my custom entity is fully invisible, and I don't know why.

I tried remaking, fixing, and re-importing the model, I tried remaking, fixing, and re-importing the texture, I tried remaking the entire entity, I checked all of the procedures related to it, but nothing works.

I also tried regenerating and rebuilding the workspace, but that didn't work either

If someone could help be, that would be really helpful, since this entity is really important to my mod.

Any help would be greatly appreciated!
