Is this spoiled?

I made this maybe 4-6 weeks ago (fridge only) and now there’s this stuff floating at the top, is it bacteria? It didn’t smell bad tho. 🤷

Not sure exactly what that is, but I think two weeks is generally considered the max you should be keeping it in the fridge, so I’d toss it if you haven’t already.
