I fixed it roughly 2 hours ago. The reason:
I made the SymPy module unbuilt, so that it didn't have to be imported and therefore mentioned in the requirements, as its recipe is broken. I completely forgot that SymPy also may have different extentions inside. I checked them, added to the extentions in the buildozer.spec and it helped.
