vscode: Extension tab doesn't work

• VSCode Version: 1.40.2 (also tested with 1.41.0-insider 2019-12-06)
• OS Version: Ubuntu 18.04

Steps to Reproduce:

1. Open VSCode
2. Open the extensions tab
3. The extensions tab seems to be endlessly loading, without any result appearing on screen, whether it be installed extensions or searched extensions.

Note that extensions work. What doesn’t work is the extensions tab. I cannot install/uninstall/search for extensions but extensions I had installed previously do work. Example: Gitlens works: it displays informations of the last commit affecting the current line:

I tried installing an extension with the appropriate command (ext install hoovercj.vscode-power-mode) but it also doesn’t work:

Does this issue occur when all extensions are disabled?:

Yes
