why don't they accept the images I create locally on my computer using the qwen model?

Submit the same assets to the community that you submit to Adobe Stock.
The thumbnails are too small to see clearly.

You were given a reason for each rejection, most likely “quality issues” or “similars”. Anyway, we can’t evaluate these tiny thumbnails for potential issues. Certainly, AI images with robots are already available in the database in vast quantities. Other than submitting flawless images, the main challenge these days with AI images is avoiding rejection based on “similars” by finding themes that aren’t already over-represented in the database.

Maybe because of errors in those files? Check for artefacts like rendering issues.
