[NEST Users] Problem with "import nest"

Hello, I have instaled NEST 3.3 (on a Rocky Linux 8.5) from source. After entering python and executing "import nest" I receive the following error. It looks like cannot load some neuron models. I tried to install last git version, but problem persist. Please, some idea? Thanks a lot in advance Xavier python: /home/neurobit/src/nest-simulator/nestkernel/model_manager.h:321: size_t nest::ModelManager::get_num_connection_models() const: Assertion `connection_models_[ 0 ].size() <= invalid_synindex' failed.
