Compiling a circuit with QJIT that begins with a CosineWindow state preparation results in a compiler error. This is because Catalyst has optimizations for when the first operation is a state preparation, but these optimizations are not supported for CosineWindow. A workaround is to only perform the state preparation optimizations on the StatePrep and BasisState classes, rather than the more general StatePrepBase class.
This workaround requires additional changes to Catalyst (PR #1166) and PennyLane (PR #6318).
