Can't run any test. java.lang.ExceptionInInitializerError, Caused by: java.lang.IllegalArgumentException

Every time when I try to run the android test(IOS doesn't try), the test failed with the following errors

java.lang.ExceptionInInitializerError

Start with the stack trace at CheckWorking.java:10 and follow the initialization path through TestBase and CommonUtils, then compare the Android configuration loading and capability setup shown in the report. Reproduce the Android test with the supplied environment and Appium logs; done means identifying and resolving the cause of the initializer failure.
