Hi @Starry1024, sorry for the late response. It's possible that you're getting this error because your CPU doesn't support AVX2 instructions, which Secure XGBoost uses to speed up oblivious computation.

Please try turning the build option for AVX2 in the CMake (linked above) to OFF, and rebuilding.
