EOFError exception raised for unknown reason

[BabakAmini]

Here is a simple code to test the apply() method, but it ended up with an EOFError exception:

import asyncio
from aiomultiprocess import Pool

async def worker():
    pass

async def main():
    async with Pool() as pool:
        tasks = [pool.apply(worker) for i in range(5)]
        await asyncio.gather(*tasks)

if __name__ == "__main__":
    asyncio.run(main())

Here is the output:

What am I doing wrong?

• OS: Ubuntu 20.0.4 running on a cheap VPS with 1 core CPU and about 1.3 GB of free RAM
• Python version: 3.12
• aiomultiprocess version: 0.9.0
