Jmeter 5.4-线程[AWT-EventQueue-0,6，main]中的java.lang.NullPointerException

尝试使用最新的Jmeter版本5.4，但是当使用Blazemeter将录制的脚本导入Jmeter并尝试禁用/执行Jmeter UI上的任何操作时，出现以下错误

Uncaught Exception java.lang.NullPointerException in thread Thread[AWT-EventQueue-0,6,main]. See log file for details.

我有Java8，早期的Jmeter版本运行良好。仅以最新版本面对此问题
