Javascript react本机应用暂时冻结，性能调试器中没有活动

这很难调试，因为发生此冻结时，chrome性能调试器中没有任何活动。ScrollView仍然会滚动，所以落后的不是Android。另一方面，性能监视器仍然显示JS为60fps，并且不会冻结

也许这是因为异步代码没有返回，尽管同步代码应该继续运行。当我提交更改时，其他操作（如向后导航）也会被阻止，尽管整个流程也是异步的

如果我试图在滞后时触摸某些东西（如更改选择），应用程序可能会崩溃，并出现以下错误：

无法记录没有触摸开始的触摸结束。

所以我的部分问题是；除了Chrome调试器和性能监视器之外，我如何调试性能

另一部分是,；为什么异步代码可以阻止应用程序，我如何防止这种情况

任何其他可能有帮助的意见也将不胜感激

顺便说一句，我花时间优化了所有以前慢的东西，所以当它不落后的时候，一切都很快
