centos7+python3.11 Segmentation fault

[Destiny]

Describe the bug
When we use python3.11 in centos7 to run sslyze, we got a "Segmentation fault".
When we use faulthandler module, it seems to be an error in nassl.

To Reproduce
Below is the test code:

import faulthandler
faulthandler.enable()
from sslyze import (
    ServerScanRequest,
    ServerNetworkLocation,
    ServerHostnameCouldNotBeResolved,
    ServerScanStatusEnum,
    ScanCommandAttemptStatusEnum,
    Scanner,
    ServerScanResult,
)

Then run the test code:

python311 xxx.py

The error is shown as below:

Fatal Python error: Segmentation fault
