That appears to be a invalid key, I assume the P8 Key is incorrectly formatted

Are you reading the key directly from the file?
Did you copy the p8 file contents to another file that contains your app settings?

If you find yourself in the second point my recommend reading the p8 file directly to avoid any issues, with this I'm also assuming that you have the correct Private Key ID

I also might be wrong but I think you don't need any of those configurations on the HttpClient as CorePush will handle it

Actually the authorization header is set when you call SendAsync

// From "CorePush/Apple/ApnSender.cs" line 85
message.Headers.Authorization = new AuthenticationHeaderValue("bearer", GetJwtToken());

My recommendation would be to try something like this

ApnSettings apnSettings = new ApnSettings() {
    P8PrivateKey = File.ReadAllText("yourp8file.p8"),
    P8PrivateKeyId = _apnNotificationSettings.P8PrivateKeyId,
    TeamId = _apnNotificationSettings.TeamId,
    AppBundleIdentifier = _apnNotificationSettings.AppBundleIdentifier,
    ServerType = _apnNotificationSettings.ServerType
};
HttpClient httpClient = new HttpClient();
string deviceToken = userDevice.DeviceId;

AppleNotificationRequest notification = new AppleNotificationRequest(Guid.NewGuid(), notificationRequest.Body, notificationRequest.Title);

var apn = new ApnSender(apnSettings, httpClient);
var apnSendResponse = await apn.SendAsync(notification, deviceToken);
// [rest of your code]
