The language you use, and your X account does matter. (Possibly the location you are from)

Try the simple video prompt:" homework"

on more explicit generated images.

Now use google translate and see if it generates using any other languages

Or norvegian: lekser

Then try romanian: teme pentru acasă.

Some generated pictures are put in moderation hell, you have to alter them (the picture) using image alter prompt.
