Fatal error condition occurred in aws-c-io
Hi ! Are you having this issue only with this specific dataset, or it also happens with other ones like `squad` ? @lhoestq It happens also on `squad`. It successfully downloads the whole dataset and then crashes on: 

```
Fatal error condition occurred in D:\bld\aws-c-io_1633633258269\work\source\event_loop.c:74: aws_thread_launch(&cleanup_thread, s_event_loop_destroy_async_thread_fn, el_group, &thread_options) == AWS_OP_SUCCESS
Exiting Application
```

I tested it on Ubuntu and its working OK. Didn't test on non-preview version of Windows 11, `Windows-10-10.0.22504-SP0` is a preview version, not sure if this is causing it. I see the same error in Windows-10.0.19042 as of a few days ago:

`Fatal error condition occurred in D:\bld\aws-c-io_1633633258269\work\source\event_loop.c:74: aws_thread_launch(&cleanup_thread, s_event_loop_destroy_async_thread_fn, el_group, &thread_options) == AWS_OP_SUCCESS`

python                    3.8.12          h7840368_2_cpython    conda-forge
boto3                     1.20.11            pyhd8ed1ab_0    conda-forge
botocore                  1.23.11            pyhd8ed1ab_0    conda-forge

...but I am not using `datasets` (although I might take a look now that I know about it!)

The error has occurred a few times over the last two days, but not consistently enough for me to get it with DEBUG. If there is any interest I can report back here, but it seems not unique to `datasets`. I'm not sure what `datasets` has to do with a crash that seems related to `aws-c-io`, could it be an issue with your environment ? > I'm not sure what `datasets` has to do with a crash that seems related to `aws-c-io`, could it be an issue with your environment ?

Agreed, this issue is not likely a bug in datasets, since I get the identical error without datasets installed. Will close this issue. Bug in `aws-c-io` shouldn't be in `datasets` repo. Nevertheless, it can be useful to know that it happens. Thanks @leehaust @lhoestq  I have also had this issue since a few days, when running scripts using PyCharm in particular, but it does not seem to affect the script from running, only reporting this error at the end of the run. I also get this issue, It appears after my script has finished running. I get the following error message

I don't get this issue when running my code in a container, and it seems more relevant to PyArrow but thought a more complete stack trace might be helpful to someone
 I created an issue on JIRA:
https://issues.apache.org/jira/browse/ARROW-15141 @CallumMcMahon Do you have a small reproducer for this problem on Linux? I can reproduce this on Windows but sadly not with linux.
## Describe the bug
Fatal error when using the library

## Steps to reproduce the bug
```python
from datasets import load_dataset
dataset = load_dataset('wikiann', 'en')
```

## Expected results
No fatal errors

## Actual results
```
