XAMPP无法连接MySQL数据库及phpMyAdmin访问失败问题求助

大家好，我现在碰到了一个棘手的问题：用XAMPP控制面板启动MySQL服务器后，服务器看起来运行状态正常，但点击面板上的Admin按钮打开phpMyAdmin时，浏览器直接报错。

先给大家贴一下最近一次启动MySQL的日志，我反复看了好几遍，没发现明显异常：

不过当天早上第一次出现问题时，错误日志里有这些异常内容：

2023-06-20 09:37:32 0x2b382023-06-20 09:37:32 0x86bc  InnoDB: Assertion failure in file D:\winx64-packages\build\src\storage\innobase\os\os0file.cc line 6154

除了phpMyAdmin的问题，我在Visual Paradigm里测试数据库连接也失败了；而且用Eclipse开发Java Web应用做数据库操作（比如创建用户）时，控制台每次都会弹出这个错误：

Cannot connect to database
java.sql.SQLException: null,  message from server: "Host 'localhost' is not allowed to connect to this MariaDB server"

还有个让我困惑的点：我明明选的是InnoDB作为存储引擎，为什么错误提示里说连接的是MariaDB服务器？

另外，我完全没有修改过数据库或服务器的配置，上次能正常连接到现在没动过任何设置，连接用的IP是127.0.0.1，端口是3306。

有没有大佬能帮我分析下这是怎么回事？万分感谢！
