@P3p111n0 the error looks like incorrect IGC version, the IGC::IgcFeaturesAndWorkarounds<4> interface has been added in intel/intel-graphics-compiler@c6068a8 it is available in IGC since v2.26.0, our release 26.09.37435.1 has been built against intel/intel-graphics-compiler@v2.30.1

Please try to upgrade IGC component
