it may relate to #2117

the operation in GetLastestMsgId is trying to the last entry message id in a stream

var latestMsg = await db.StreamRangeAsync(_typedCacheConfig.Subscription, count: 1, messageOrder: Order.Descending);
return latestMsg.Length > 0 ? ((string?)latestMsg[0].Id) : string.Empty;

Redis server version: 6.0.5
StackExchange.Redis version: 2.2.4 on .NET 6

it will be unrelated to 2117 - that's a separate connection and scenario; is this repeatable, i.e. can you repro this reliably on demand? or is this very rare and hard to repro?

For clarification; ^^^ is also me; I'm testing options to help with the "MSFT touched my GitHub account and now I can't see half of them" single-signin problem.
