problems installing OS 12

Each time I've attempted to install OS 12 on my Mac Pro (Late 2013) it stalls halfway thru the installation.

No way to recover except hard restart, then start up in recovery mode. Erase the hard drive, reinstall OS 11 and retrieve my latest backup. I'm waiting for a resolution until I attempt to upgrade to OS 12 again.

Mac Pro, macOS 11.6
