Solved! At least for me... I am using Visual Studio 2022 and ArcGIS Pro 3.1.2. Windows 11.  followed this guide: https://youtu.be/0HuXF_lJY0o?si=FId8Gk7XVKW-klcC

I got the same error as the original post. In Visual Studio, I forgot to change the ArcGIS Pro Python Toolbox .pyt file property "Copy to Output Directory" value from 'Do Not Copy' to 'Copy Always'. See attached picture.
