Xcode 15.0 Beta 6 is unusable due to hanging installation and attaching phases

The previous betas have all been ok, but beta 6 is for me totally and utterly unusable because it keeps hanging forever during the installation and attaching phases when trying to run an app (attached physically via cable, not bluetooth).

The first time or two of making a code change, then running, its ok, but then its guaranteed to hang eventually, it gets stuck on the "Installing app to iPhone" phase. If I restart the phone and try again it might get past that, but then it just gets stuck on "Waiting to attach to app on iPhone" phase.

I know its beta software and not expected to be perfect, but its unusable and previous beta versions are no longer available to rollback to. Has anybody encountered this before and knows of any tricks to get it to stop hanging and load/run the app? (Restarting Xcode, restarting the phone, re-building, does not fix it for me)

So I deleted Xcode and re-installed it, and also used a different phone, the result is the exact same thing - Xcode says "Installing app" forever, literally forever. Its unusable.
