Hello,
i recently rebuild protobuf on my system, and now i get the following error when using something that uses protoc:

~> kicad
/usr/bin/kicad: symbol lookup error: /usr/lib64/libkiapi.so.9.0.0: undefined symbol: _ZN6google8protobuf8internal14UntypedMapBase13EraseFromTreeEjN4absl12lts_2024072218container_internal14btree_iteratorINS5_10btree_nodeINS5_10map_paramsINS1_10VariantKeyEPNS1_8NodeBaseESt4lessIS9_ENS1_12MapAllocatorISt4pairIKS9_SB_EEELi256ELb0EEEEERSH_PSH_EE

Does anyone know how to fix this? Also here are my settings with which i build protobuf:

# Catalyst-generated base configuration
