I hope somebody could help me debug this issue

Solution 1:[1]

I think your system got update of the Java runtime to some new version which is not compatible with your version of JMeter.

Try downgrading your Java, the minimal version you can run JMeter 5.4 is Java 8

Solution 2:[2]

If you have installed two versions of java 8 or 11, Then please switch to lower version 8 and then run tests. This solution worked for me
