Your setup is clearly trying to use Java 11 when Autopsy requires Java 8.
You must have missed one (or more) of the steps in the document related to Java installation.
I suggest going back over all of the steps related to Java to ensure that you use the correct version.

Thank you so much for replying.
I apologize missing this sentence.

Uninstall any JDKs currently installed on the system.

I resolved this problem following steps.

  1. I checked all JDKs installed on my PC
    $./usr/libexec/java_home -V
  2. I removed all JDKs expect liberica-jdk8-full
    $sudo rm -f /Library/Java/JavaVirtualMachines/jdk...

Now I’m ready to learn Autospy​:dog::mag_right:
