There's something messed in your configuration. You are reporting the use of Java 17.0.6 and nextflow 23.10.1.

However the logs says Nextflow 22.04.5 and Java 18.0.1.1

I had this error quite a lot about 18 months ago but solved it by using java=11.0.1 in a conda environment.

On Linux I also had to unset any conflicting java env settings and potentially also reset JAVA_HOME to the one I wanted to use

# Setup java env 
unset JAVA_HOME
unset _JAVA_OPTIONS
unset JAVA_OPTIONS

You can check your java envs on Linux with

env | grep JAVA
