The appium startup keeps reporting errors.
Various errors, such as.

[debug] [ADB] Creating ADB subprocess with args: ["-P",5037,"-s","192.168.0.4:5555","shell","am","instrument","-w","io.appium.uiautomator2.server.test/androidx.test.runner.AndroidJUnitRunner"]

or:

The appium.setting installed on the device doesn’t open manually either, and I always thought that was the reason.
Tried to re-install appium and node version, still not working. Finally, here is the solution below:

if automation_name =='UiAutomator2':
    desired_cap['uiautomator2ServerInstallTimeout'] = 20000 This time is changed from 9000 to 20000 and it's fine. It started successfully. After a week of problems, finally good.
