Hello @MothMan,
Thank you for taking time to post this issue in Microsoft Q&A forum.
Please try to check the limitations on your machine, such as antivirus, proxy, security management software and group policy. Make sure that you have enough rights to access to the network and download the extensions. Run the VS Code as administrator.
Also, try to clean some cache folders under C:\Users\username\.vscode\extensions
and C:\Users\username\AppData\Roaming\Code
(Cache, CachedData, CachedExtensions, CachedExtensionVSIXs and Code Cache).
Since VS Code is different from VS IDE, and currently VS Code is not supported on the Microsoft Q&A forum, if above methods don’t work, please kindly post your question on GitHub - vscode for further help.
Thanks for your understanding, have a nice day:)
Best Regards,
Tianyu
