It looks like another software package had installed an old version of parallel in a conda environment, that was being called instead of the parallel in my WSL2Ubuntu install. The software developer for the program that was having the
issue, genome_updater, gave me a command to update the conda environment that seems to have solved the crash.

Not certain what is happening but this command has been working for a year or more in WSL2Ubuntu on a Win 11-64bit machine (fully updated). I just did a sudo apt upgrade when I
started this time and several packages were updated. The screen output is as follows, and I was not using the -p switch for parallel.
