This question deals with discord.py errors caused by asyncio, but any advice on creating discord bots would be very welcome. I am more than willing to read documentation to fully understand responses, and will pursue provided articles.
Problem:
I am attempting to create a simple discord bot in python 3.9. I am new to python, and have been using pycharm to write my scripts. I found an error while attempting to run the script. Script provided here:
import discord
client = discord.Client()
@client.event
async def on_ready():
print('We have logged in as {0.user}'.format(client))
@client.event
async def on_message(message):
if message.author == client.user:
return
if message.content.startswith('$hello'):
await message.channel.send('Hello!')
client.run('my bot token')
Error provided here:

SyntaxError: invalid syntax
Solutions I've Seen So Far:
I have seen a myriad of questions asking the same for python 3.7, and none for 3.9. This would either be because nobody else experiences the same error with python 3.9 in pycharm, or the solution is the same as in python 3.7.
I have seen many people recommending dropping to version 3.6 of python because async is a keyword in 3.7, which I want to avoid if possible. I'm fairly sure it still is a keyword in 3.9.
Some responses have said that pycharm creates virtual environments and would not have discord.py installed. This is not true in my case -- I have checked my project preferences and discord.py is in fact included and accessible by my script. More evidence is in the error message: the line causing problems is found in the discord.py directory, so the compiler must be able to access it. Right?
The problem may arise from the fact that i installed using pip install discord.py and then tried again with pip3 install discord.py. As far as I can tell, these worked as intended. There is an error if i try to use pip3 install discord or pip install discord, which I have provided. I do not know if the .py makes a difference, but if it does, i'm sure it would help to know that. The only other version of a solution i've seen is downloading the rewrite version of discord.py off github. I have not tried this yet because i want to make this version work if possible.

Questions:
Has anyone had success with discord bots in python 3.9?
Is something wrong with my script?
Is async a keyword in python 3.9? If so, how can i modify my program to solve this problem?
How can I fix this issue without downgrading to python 3.6? Is that the only way?
Why does pip install discord not work? What are wheels? I do not want to install C++ build tools.
Would it be easier to program a bot in C++ or JS? I don't know any JS but i am familiar with C++.
Any help with this issue would be massively appreciated. Also, as this is my first stack overflow post, please feel free to let me know if i could have done anything better in asking this question. if there's anything else i can provide to help you wonderful developers who are willing to spend their time solving noob problems like this one, please let me know.
Also, if willing and able, please provide some tips for writing discord bots. This is intended to be a small Admin bot created to test and develop my python skills. Interaction with people is the focus, not automation of any kind, although I do want to try out as many ideas as possible.
Edit:
Included PyCharm python interpreter settings.
Also had an issue with opening a new venv project and installing discord.py to it. Same wheels error as above, provided errors and other relevant windows in the image below. also not sure where to put my script file or how to make the run configuration.
