Nvidia video effect sdk bug

On the same PC, Win11
I run the DenoiseEffectApp in vs2019 64bit. in DenoiseEffectApp sample,it loads Denoise-con-89.engine.trtpkg automatically.
but in my qt project(vs2019 64bit compiler), it loads Denoise-agg-89.engine.trtpkg…and the NvCVImage_Transfer failed:-800(CUDA tried to load or store on an invalid memory address).
why the sdk used two different models?how to use agg model?
