Please follow these steps

• Help -> Toggle Developer Tools -> Network
• Then check for any network failed requests while browsing and installing the extensions if found all requests fails then its probably a proxy or DNS issue at your end.
• To confirm its a DNS issue check if you can access this page https://ms-python.gallerycdn.vsassets.io/extensions/ms-python/python/2019.8.29288/1565127378610/Microsoft.VisualStudio.Services.Icons.Default, if you cannot please try configuring your DNS like pointing to 1.1.1.1 as suggested here? https://1.1.1.1/dns/. Otherwise please contact your network administrator.
• If it is not a network issue, please share the logs from the following locations
  • Help -> Toggle Developer Tools -> Console
  • Help -> Toggle Shared Process -> Console
  • View -> Open View… -> Log (Shared)
