Importing a Python Toolbox (ArcGIS Pro 2.9)

Question

I'm not sure what I'm doing wrong with arcpy.ImportToolbox() in ArcGIS Pro 2.9. No matter what I do, it always errors with

OSError: The toolbox file C:	emp\MyToolbox.pyt was not found.

There's not much to it besides calling arcpy.ImportToolbox(). What am I missing?

Here's sample code that worked in ArcMap, but I have not tested in Pro.

# standard python toolbox formatting for your utility toolbox
# C:/path/to/this/toolbox.pyt
class Toolbox(object):
    def __init__(self):
        self.label = 'your label'
        self.alias = 'some_alias'
        self.tools = [tool1, tool2, tool3]

# later on when you want to call them, e.g. from another .pyt
ImportToolbox(input_file='C:/path/to/this/toolbox.pyt')
arcpy.some_alias.tool1(arg1, arg2, ...)
arcpy.some_alias.tool2(arg1, ...)
arcpy.some_alias.tool3(arg1, ...)

I don't have that problem with "custom" toolboxes.  It may be a solution.  Although, I tend to have my own *.py file imported by the toolbox, which may contain esri tools, rather than importing them directly

And to clarify further, I currently have the utility functions in their own .py file that is imported into each individual tool's .py file. This is working, but I'd like it to be in the Python toolbox .pyt file so I can encrypt it.
