NetExec info
- OS: Ubuntu 20.04.1 LTS
- Version of nxc: 1.2.0
- Installed from: pipx install git+https://github.com/Pennyw0rth/NetExec
This might be an issue with your python version and asyncio in py3.8. Do you have the option to use a more recent version of python? Maybe pyenv would be a good solution.
There was an issue in the past with rdp, asyncio and python so it might be related: https://github.com/Pennyw0rth/NetExec/issues/73
