We now bundle copilot with VS code so you shouldn't need to download a verison. As 0.48.1 is an older version of the exetnsion.

Please also attach network logs via CMD + SHIFT + P -> Chat Diagnostics

Extension: 0.48.1
VS Code: 1.117.0

May I know how you landed into having 0.48.1 version of copilot chat extension?

But I see, in the summary you mentioned VS Code version is 1.120.0 - Any reason behind this confusion of VS Code version?
