I don't know where you're getting your information from, but you appear to be out of date in a few respects. Bullseye was officially released yesterday. You should be using an installer image labeled "11.0", not one labelled "rc2" (release candidate 2). In fact, I don't even think that was the final release candidate. I thought there were at least 3 of them, possibly more. It's quite possible that the issues you encountered were fixed after that release candidate image was created.
