VBA程序在删除行时卡死的原因可能有以下几点：
1. **事件递归**：在`Worksheet_Change`事件中，删除行可能会触发另一个`Worksheet_Change`事件，导致递归调用。虽然你已经使用`Application.EnableEvents = False`来防止递归，但在某些情况下，事件可能仍然会被触发。
2. **全局变量**：`IsDeleting`变量用于标识是否正在删除行，但在`DeleteRows`子程序中，可能没有正确地设置或重置这个变量，导致逻辑错误。
3. **隐藏行检测**：`IsDeletingRows`函数通过检测行是否隐藏来判断是否正在删除行，这种方法可能不够可靠。
以下是一些建议来解决这个问题：
- 确保在所有可能的退出路径中都正确地重置`Application.EnableEvents`和`IsDeleting`变量。
- 检查`IsDeletingRows`函数的逻辑，确保它能够准确地检测到删除行的操作。
- 在`DeleteRows`子程序中，确保在删除行之前和之后正确地设置和重置`IsDeleting`变量。
如果问题仍然存在，建议逐步调试代码，查看具体在哪一步出现了卡死的情况。
