Fail to build my target all of a sudden

Today, I just update a few files for minor modification, and build my target in Xcode, it suddenly comes out the following error message:

line 146: 30102 Abort trap: 6 UE_BUILD_FROM_XCODE=1 dotnet Engine/Binaries/DotNET/UnrealBuildTool/UnrealBuildTool.dll $TARGET $PLATFORM $CONFIGURATION “${TRAILINGARGS[@]}” $UBT_ARCHFLAG $AdditionalFlags

Command ExternalBuildToolExecution failed with a nonzero exit code

I’ve never seen such error before, it seems like the UBT itself fails at some point, before this, my target can be built successfully. Could anyone give some help/advices on this? Thanks in advance, I’m using UE5.6.1.
