module 'asyncio' has no attribute 'coroutine' on snakemake

I followed the following code to install snakemake on my linux machine :

conda activate base
mamba create -c conda-forge -c bioconda -n snakemake snakemake
conda activate snakemake

Everything was fine, but when I try to run the following code :

snakemake -s Snakemake_job -j n

I get this error :

Building DAG of jobs...

    __aexit__ = asyncio.coroutine(__exit__)
                ^^^^^^^^^^^^^^^^^
AttributeError: module 'asyncio' has no attribute 'coroutine'

Does someone have an idea of what is going on? I tried to re-install snakemake, or to pip install asyncio without sucess...

Quoth the docs for asyncio.coroutine, emphasis mine:

Deprecated since version 3.8, will be removed in version 3.11: Use async def instead.

The ratelimiter dependency snakemake uses is evidently not compatible with Python 3.11.

That package has had an issue open about this for multiple years, and snakemake seems to be switching dependencies.

In other words, your choices are:
