Your query is not connected to JMeter Plugins by any means, going forward please look for help on JMeter issues at JMeter Forum

Coming back to your issue, it sounds like a JMeter Bug 65300 so you have the following options:

1. Downgrade your JRE to Java 8, it's the minimum sufficient version to run JMeter 5.4
   
2. Upgrade your JMeter to a nightly build
3. Replace line 112 of the jmeter.bat startup script with the following one:

set JAVA9_OPTS=--add-opens java.desktop/sun.awt=ALL-UNNAMED --add-opens java.desktop/sun.swing=ALL-UNNAMED --add-opens java.desktop/javax.swing.text.html=ALL-UNNAMED --add-opens java.desktop/java.awt=ALL-UNNAMED --add-opens java.desktop/java.awt.font=ALL-UNNAMED --add-opens=java.base/java.lang=ALL-UNNAMED --add-opens=java.base/java.lang.invoke=ALL-UNNAMED --add-opens=java.base/java.lang.reflect=ALL-UNNAMED --add-opens=java.base/java.util=ALL-UNNAMED --add-opens=java.base/java.text=ALL-UNNAMED --add-opens=java.desktop/sun.awt.shell=ALL-UNNAMED
