Imaginei que não fosse isso, já que no terminal dá só a mensagem de segfault, mas ele mostra alguns warnings sobre os drivers de vídeo no log
Eu instalei pelo app do itch, que baixou uma atualização hoje, e baixei manualmente uma cópia do site e rodei, e o problema foi o mesmo.
O log tem vários eventos de carregamento de bibliotecas e debug de threads, posso enviar completo, mas a última parte (que indica o erro) é a abaixo.
