Why can't my texture be read?

I have been working on this for the past 2 days and I’m not sure I should continue with it, for some reason the output gives this.

LogStreaming: Warning: Failed to read file '/Game/Textures/transparent_test.transparent_test' error. LogSlate: Could not find file for Slate resource: /Game/Textures/transparent_test.transparent_test

It’s like it sees the asset and it cannot read it? I don’t know what else to do.
