问题原因： 这个问题和锁屏时google新增的动画处理逻辑相关。 之前版本中，锁屏后无限循环的动画依然会触发，谷歌对这个问题进行了处理；这个处理导致Android13上的动画会崩溃并报错。

163      * If animators are not properly disabled when activities are backgrounded, it can lead to
164      * unnecessary processing, particularly for infinite animators, as the system will continue
165      * to pulse timing events even though the results are not visible. As a workaround, we
166      * pause all un-paused infinite animators, and resume them when any window in the process
167      * becomes visible.

复现方法："router_uri":"hap://app/com.lingmao.quickapp/reader?_PARAM_PAGEANIMATION=%7B%22openEnter%22%3A%22none%22%2C%22closeEnter%22%3A%22none%22%2C%22openExit%22%3A%22none%22%2C%22closeExit%22%3A%22none%22%7D&recommended_position_name=deeplink&chapterId=&last_page=%E9%A6%96%E9%A1%B5&recommended_page_name=&recommended_position_id=&recommended_plate_name=&bookId=221195" 使用这个uri进行跳转，然后过滤日志 ExtensionManager，在快应用打开，图标闪过白屏的时候立刻切到后台，这时候日志如果显示调用了system.animation enable/play 方法，等待10s中左右框架就会崩溃
