Unable to start JMeter after installing internal plugin.

**Rohit Sarkar** ([Bug 66045](https://bz.apache.org/bugzilla//show_bug.cgi?id=66045&redirect=false)):
After installing a internal plugin in JMeter, when I am again starting JMeter its showing error.

****BELOW IS THE MENTIONED ERROR*****

2022-04-29 14:38:21,201 main ERROR Error processing element GuiLogEvent ([Appenders: null]): CLASS_NOT_FOUND
2022-04-29 14:38:21,405 main ERROR Unable to locate appender "gui-log-event" for logger config "root"
An error occurred: 'java.util.Vector org.apache.commons.cli.avalon.CLArgsParser.getArguments()'
errorlevel=1
Press any key to continue . . .

When I am installing the internal plugin the below mentioned file is being over written.
Overwrite E:\apache-jmeter-5.4.3\lib\ext\ApacheJMeter_core.jar

Can anyone help me regarding this.

I am attaching the screenshots and the plugin .bat files.
