保存时cmd中的报错信息，如下2种：
Uncaught Exception java.lang.IllegalAccessError: class com.github.weisj.darklaf.ui.filechooser.DarkFilePaneUIBridge$DetailsTableModel (in unnamed module @0xd83da2e) cannot access class sun.awt.shell.ShellFolder (in module java.desktop) because module java.desktop does not export sun.awt.shell to unnamed module @0xd83da2e in thread Thread[AWT-EventQueue-0,6,main]. See log file for details.
Uncaught Exception java.lang.NoClassDefFoundError: Could not initialize class org.apache.jmeter.gui.util.FileDialoger in thread Thread[AWT-EventQueue-0,6,main]. See log file for details
2、修改jmeter 配置文件
解决方法
如图找到jmeter.bat 或 jmeter.sh文件，用记事本打开大约110行左右的位置，添加红框内容，即：--add-opens java.desktop/sun.awt.shell=ALL-UNNAMED 即可解决。
重启jmeter 即可
