This is a known macOS environment issue related to conflicting dynamic libraries (libAdskSeExpr.dylib) loaded by Maya and Arnold, coupled with macOS's strict @rpath dependency linking.The CulpritArnold’s XGen procedurals are attempting to load libAdskSeExpr.dylib. However, because it's listed in a local path /Applications/Autodesk/maya2027/Maya.app/Contents/Frameworks/, macOS's dyld search order picks up older or clashing versions in your system's Application Support folder or Maya's path instead of the correct Arnold/Maya framework location.
