terminate called without an active exception
Aborted (core dumped)

Get same problem when I use pip install brainflow or when I compile from source.

To Reproduce
To report a bug you need to create a simple example that uses only BrainFlow API or use one of the tests we already have. In this example, you need to call enable_dev_board_logger () and share the output with us. Also, make sure the latest version is used.

See command and terminal output above

Info (please complete the following information):

• Board Id: 38,39
• OS running on your PC: Ubuntu Linux
• Programming Language and its version: Python
• Architecture(x86, x64, ARM, etc): x86_64
• In case of Python full output of pip list command, for other languages please provide BrainFlow version used

(brainflow_pip) kernel@stoic-hofstadter:~/Code/eegnb_dev/brainflow$ pip list
Package    Version
---------- ---------
brainflow  4.8.2
certifi    2021.10.8
nptyping   1.4.4
numpy      1.22.0
pip        21.2.4
setuptools 58.0.4
typish     1.9.3
wheel      0.37.0

Expected behavior

• A clear and concise description of what you expected to happen
• The above command to connect with out crashing.

Screenshots
If applicable, add screenshots to help explain your problem.

Additional context
I noticed that when running the above command, the muse device first connects (stops flashing), and continues to be connected after the core dump.

I did notice that this comp has in its config description 'virtualization: AMD-V`. Not sure if that is relevant here.

Welcome to BrainFlow project and thanks for your contribution! We will try to fix your issue ASAP. Make sure that you have read about issue format in the docs.

@JohnGriffiths I have no ubuntu, tested on raspberry and could not reproduce. There was a huge update in underlying BLE library especially for linux in #408. Could you test it from this branch? Need to build from source using python3 tools\build.py --ble and install python binding from a local folder using cd python-package && python3 -m pip install -U .
