It seems to be caused by the fact that async is (now?) a reserved keyword and can't be used as a variable name.  
I was able to get webiopi to start by replacing the variable name async with async_ in the function runLoop in the file /usr/local/lib/python3.7/dist-packages/WebIOPi-0.7.1-py3.7-linux-armv6l.egg/webiopi/utils/thread.py .  Function runLoop now looks like this:

def runLoop(func=None, async_=False):
    global RUNNING
    RUNNING = True
    signal.signal(signal.SIGINT, stop)
    signal.signal(signal.SIGTERM, stop)

    if func != None:
        if async_:
            TASKS.append(Task(func, True))
        else:
            while RUNNING:
                func()
    else:
        while RUNNING:
            time.sleep(1)

I created a new patch that supports Raspbian Buster and Raspberry Pi 4.
Please see the instructions below.


Please use it until the pull request to the doublebind's one is merged.
