I searched a lot on the Internet, but I couldn't find a solution
It is best not to try the commands in this post. It is best to take a snapshot of your virtual machine. After the following commands are executed, you will not be able to find the network settings.
Solution:

If there is no problem with ping, then there is a problem with the shell
