Error: Error: Error: Extension [name] not found.

🐛 Describe the bug
For a clean version, vscode installed the SyncSettings extension. Trying to download my settings from the gist. Gives the error "Error: Error: Error: Extension [name] not found." I went to the gist and manually removed the extension that the plugin could not install. I'm trying to set the settings on a new one: the result, only now, cannot find the next extension.

There is no such problem.

upd:
I jumped to conclusions.
This problem exists here, only this version managed to install more plugins before getting the error.
