I emailed you the error log I see when trying to run the jar on macOS 10.14. It contains more errors than the log that trungdq88 posted does.

Oh, whoops, I see that the Download page says JRE 11 or newer must be installed. My JRE version was 8 (Java 1.8).

After switching to OpenJDK 14, I get the same errors as trungdq88.
