in a fresh project im trying

#[tokio::main]
async fn main() {
    let mut shard = Shard::new(
        ShardId::ONE,
        "<TOKEN_REDACTED>".to_string(),
        Intents::GUILD_MESSAGES
    );
}

and i'm getting a TlsError { kind: Loading, source: Some(MissingOrMalformedExtensions) } (full stacktrace: https://paste.rs/7Yegq.txt)
here someone else had the same problem: https://discordapp.com/channels/745809834183753828/745815089067851807/974406718320697434
but unlike for them, the suggested solution didn't work for me (i tried all 3 TLS features)
any ideas? @urban wasp did you ever figure this out?

You need to disable default features to be able to switch the TLS backend

#

The error is saying something along the likes of "your OS' certificate store is faulty". The rustls-webpki-roots feature should work as it's totally independent from your OS

forgot about disabling default features. webpki does work fine. any idea how to fix the os certificate store on windows?
