Importing library 'SerialLibrary' failed

Uninstalled PyCharm IDE, RIDE, Robot Framework and libraries.
Reinstalled PyCharm IDE and Robot Framework. I am not using VENV, and using the base python interrupter for the project.

Installed the serial library using the PyCharm project’s terminal window.
PS C:\Development\robot-scripts\pythonProject\IOT> pip install robotframework-seriallibrary
Collecting robotframework-seriallibrary
Using cached robotframework_seriallibrary-0.4.3-py2.py3-none-any.whl (9.7 kB)
Requirement already satisfied: install_requires in c:\users\gordo\appdata\local\programs\python\python310\lib\site-packages (from robotframework-seriallibrary) (0.3.0)
Installing collected packages: robotframework-seriallibrary
Successfully installed robotframework-seriallibrary-0.4.3

Project’s test file does not indicate an issue with the *** Settings *** Library SerialLibrary encoding=ascii statement

When I run it from the command line I get this

PS C:\Development\robot-scripts\pythonProject\IOT> robot -d results tests
