After updating to appium 1.20.0 UnknownError happens on every test run

The problem

Since I updated to appium 1.20.0, all my android tests trigger this error UnknownError: An unknown server-side error occurred while processing the command. Original error: Could not proxy command to the remote server. Original error: timeout of 240000ms exceeded

Code To Reproduce Issue

The code is written in ruby, it happens when I call this method and it cannot find the element: driver.find_elements(accessibility_id: 'log_ind')

Notes

• I have not modified my code before this issue happened
• I just ran my whole suite after updating to 1.20.0
• All my iOS tests works fine
• I have tried with Android API 8.1 x 86 on a Nexus 6p emulator and the issue is the same

Could you append around logs for the logcat and run with --log-timestamp for appium server to check the timeline? It is also appreciated to attach the full appium server log.

For logcat: Probably like xxxx /io.appium.uiautomator2.server I/appium: channel read: POST /wd/hub/session/yyyyy/element log exists in the logcat after getting a request.
