After creating a spark project and testing a “hello word”, I encountered the following error：

Internal error (java.lang.UnsupportedClassVersionError): org/intellij/erlang/jps/model/JpsErlangModelSerializerExtension has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0

Solution: Close the Erlang plugin and restart IDEA
Steps: Intel iJ IDEA -> Preferences -> Pluglinis -> (search Erlang) Remove the checkbox
