Я разрабатываю игру, в которой есть 4 здания, и в этих зданиях есть 3 этапа внутри. Игрок может играть на этапах один за другим, из одного здания в другое, однако, когда они закончили один цикл (например, переходя от этапа 1 здания 1 к этапу 3 здания 4), я получаю эту ошибку там, где это ошибка 14 SQLITE_CANTOPEN) всякий раз, когда игрок нажимает на другое здание. Это происходит каждый раз, когда я тестирую приложение. Может кто-нибудь мне помочь? : S
edit: извините, вот код, который я использовал, чтобы открыть окно для доступа к игре:

и вот код, который я использовал для извлечения данных из базы данных:
