@Sega2 it sounds like the error occurs because the typing_extensions library version in your Databricks environment is outdated and does not include the Buffer class, which is being imported by one of the Azure libraries.

Can you first try:

%pip install --upgrade typing-extensions

Validate it:

import typing_extensions
print(typing_extensions.__version__)

And then ensure the version is >=4.6.0, as this version supports Buffer.
