Any help would be appreciated. Thank you.

It looks like something is wrong with the Unsplash portion of your settings. Can you try removing that bit from your settings, saving the file, and uploading again?

For reference, that part of the config looks like this:

    "id": "61800b---",
    "group": "unsplash",
    "key": "unsplash",
    "value": "true",
    "type": "boolean",
    "flags": null,
