Workflows hanging, stuck on "Aborting"

Hi-

I'm having some issues with workflows hanging prior to launching any tasks. I've also noticed that even if I abort, they stick with the status "Aborting" indefinitely.

This problem has appeared with two different workflows, one seen below.

task read {
    File list

    command {
        ls
    }

    runtime {
        docker: "tmajarian/alpine_wget@sha256:f3402d7cb7c5ea864044b91cfbdea20ebe98fc1536292be657e05056dbe5e3a4"
    }

    output {
        Array[String] filepaths = read_lines(list)
    }
}

workflow w {
    File list_file
    call read {input: list=list_file}
}

This has run fine previously. Also below, an attached screenshot of the hang and stuck on Aborting.
