Imported OBJ Model has black Texture

Hi.

I am really sorry if this issue is already fixed, I tried to search about this issue but it did not help me out.

I have made a basic model in the backbench and exported it in a .obj with MTL and texture.png.

when i imported it to my Mcreator and test it, I found the block has weird black texture and something it's purple and black. I really tried my best but didn't help me out.

Here is my workspace, please help me to fix this issue
