@CKReliancd, not sure if you're still having this issue, but looking into the attached file, I see it is actually a WebP image file with a PNG extension. (In other words, the file extension doesn't match the actual file format.)

Here's the output from exiftool for the attached file:

Since by default, Java doesn't bundle support for reading/writing WebP files, Thumbnailator cannot open the file. To be able to read the file, you'll need to include a Image I/O plugin for WebP. Please refer to this FAQ for more information.
