It looks like that the version of anyio loaded by the application doesn't have the Lock attribute.

You can run the following code to verify the problem.

import anyio
print(anyio.__file__)
print(open(anyio.__file__).read())
anyio.Lock()

For more information, please refer to this discussion.

My anyio package is version 3.6.1.

anyio 3.6.1 pypi_0 pypi

Thank you for the lines of diagnostic codes. I see print(anyio.__file__) gives me None, and realize something is out of place. Although conda list in my terminal shows anyio package is installed, its path is not recognized. I uninstalled & installed the package again and it works fine now.
