Material appears in the editor but not when launched.

I’ve placed a material onto a block made with bsp bushes and when viewed in the editor or in play mode it appears perfectly fine but when I launch the level it goes away leaving the default checkerboard. The material was placed on the image and I fitted it using align surface fit. I’ve attached images showing the problem. Any help would be great. Thank you!!

Above you can see how the image should appear
And below you can see how it appears when launched.

Sorry looks like its working now. I’ll leave this up in case future people are looking for help. I must’ve moved the original file or deleted it or something but I think the file path was broken somehow. Deleting the material and texture and re uploading it fixed the issue.
