Python extension v2024.14.0 fails to start with VSCode 1.89.1

[jdamp]

Type: Bug

Behaviour

The Python extension v2024.14.0 fails to start with VSCode 1.89.1. The error message mentions: Error: The language client requires VS Code version ^1.91.0 but received version 1.89.1.

Steps to reproduce:

1. Install VSCode version 1.89.1
2. Open VSCode and install the Python extension. For me, v2024.14.0 was the version that was installed. I did not specifically select this version.
3. Create a new Python file and realize that the Python extension is not working

Additional information

I believe this issue is caused by a mismatch of the version specification between the Python extension and vscode-languageclient.
The Python extension version 2024.14.0 is compatible to "vscode": "^1.89.0-20240415" (see here: https://github.com/microsoft/vscode-python/blob/v2024.14.0/package.json#L48).
Meanwhile, the dependency vscode-languageclient is specified as "vscode-languageclient": "^10.0.0-next.12" (https://github.com/microsoft/vscode-python/blob/v2024.14.0/package-lock.json#L36)

However, vscode-languageclient 10.0.0-next.12 has a different VSCode version compatibility: "vscode": "^1.91.0"
(https://github.com/microsoft/vscode-languageserver-node/blob/release/client/10.0.0-next.12/client/package.json#L8).
Due to this discrepancy, I believe that either the version of the vscode-languageclient dependency or the VSCode version specification of the Python extension v2024.14.0 needs to be adjusted.

There is an issue with that version. You will have to update VS Code to 1.94, and install python extension 2024.16.1
