点击X图标时崩溃V1.2.0（Crashes when clicking the X icon.）

[EasonHelloWord]

问题描述（Issue Description）

使用数位笔或鼠标点击X图标会有一定概率触发崩溃事件，有种拆炸弹的美感。
（Clicking the X icon with a digital pen or mouse has a certain probability of triggering a crash event, giving it a somewhat suspenseful and delicate feel, akin to disarming a bomb.）
后附配置文件
（Ending is the configuration file.）
