About "Failed to find low stub in physical memory!" problem?

[BlueTearsY]

前期调试，可以正常找到low stub，因为一些原因，我将处理器的内核数量，由2个改为1个，再次调试时，提示 Failed to find low stub in physical memory!
In the early debugging, low stubs could be found normally. For some reasons, I changed the number of processor cores from 2 to 1. When debugging again, it Failed to find low stubs in physical memory!

经过测试：
After testing:

内核数量为2个时，low stub 一般都是在固定的物理地址：13000
When the number of kernels is 2, low stubs are usually at a fixed physical address: 13000

内核数量改为1个，无法找到low stub，使用CheatEngine搜索物理内存也无法找到low stub
The number of kernels is changed to 1. Low stubs cannot be found, nor can a search for physical memory using CheatEngine

如果你遇到了此问题，也可以将处理器的内核数量改为2个试试。。。
If you encounter this problem, you can also change the number of processor cores to 2 try...

另外，我还有个小问题，low stub是什么？
And I have a little question, what is low stub?

在系统中发挥着什么样的作用呢？
What role does it play in the system?

还请大佬给普及一下知识
