vscode: Setting `NODE_UNC_HOST_ALLOWLIST` does not work

Steps:

make sure no security.allowedUNCHosts is configured
configure an environment variable NODE_UNC_HOST_ALLOWLIST to be localhost
restart Windows
run code --user-data-dir \\localhost\c$\Users\<name>\Desktop\some-empty-folder
VS Code should open fine
open a folder such as vscode
make sure extensions work (e.g. typescript) and you can change user settings

Setting the hosts in the security settings did the trick! This also works in v1.78.2.

Thank you very much for your support 🥇

You will only have to configure NODE_UNC_HOST_ALLOWLIST in rare cases where a setting cannot be configured otherwise, for example when your VS Code application data directory is on a UNC drive. For most cases:

you can remove the variable
you open settings and find the Security entry
you add the 3 IP addresses as allowed host to the UNC host allow list

Can you wait for the 1.78.2 release later today and try again.
