Just learning automation, the Appium+Python+nox simulator uses the XPATH method to locate elements and reports an error.

When using Appium automation, the following error is reported (with code):

Whether it is SDK, JDK, and ADB are all configured, except for JDK 1.8, all other versions are the latest.
I have tried countless methods on the Internet, but I have not solved it. I have just learned something, and I am stuck here. Please help me, thank you very much!
