xCode 13 install causes iMac reboot

My new iMac is rebooting about half way into the installing phase of xCode 13. Many attempts.. always the same crash

A Feedback Assistant bug report has been filled. I can restore the last version of xCode from backup

Any ideas for a work around? Obviously no new app releases from me until xCode is running again at the 13 version

Fixed the issue and installed xCode 13 by deleting the Norton Security App.

By the way - the new permission setting procedure to enable system extensions is interesting.. It is shutdown, restart into the OS Recovery environment, then enable kernel extensions from a Security Policy button. More than one confirming admin password entry is required. It's fine with me, I like security !
