I had the same issue, but reinstalling vscode did nothing. This is what worked for me:
thanks bdlangton . It works for me .
for windows 10 users, go to user/yourusername/roaming folder, delete Code folder, restart vscode.
reason would be some cache data is broken, but I am not interested in which one exactly. but definitely not CachedExtensions folder
please do backup this folder before delete, it stores not only the extension settings, but also other settings, like which folder to reopen next time etc.
