I am trying to run the Qwen3.5-9b-int4-ov model on the NPU using openvino-genai. I am encountering a compilation error during the initialization of the VLMPipeline.

Environment:

Device: NPU

Model: Qwen3.5-9b-int4-ov

OS: Windows 11

OpenVINO version: [Insert version, e.g., 2025.x]

Error Log: [ERROR] [vpux-compiler] Got Diagnostic at loc(fused<{name = "module", type = "Module"}>["module"]) : StopLocationVerifierPass Pass failed : Found 32 duplicated names after full verification
...
RuntimeError: Exception from src\plugins\intel_npu\src\compiler_adapter\src\ze_graph_ext_wrappers.cpp:433:
