Cannot login on macOS 15.5 beta 2

just updated macos to 15.5 beta 2, cannot login anymore! i reach the login screen, i enter the correct password, the loading bar stops at around 10%, after about 1 minute the system restarts, it return to the login screens, and so on…

any suggestion about debugging this type of situation?

can you log in in Safe Mode? (https://support.apple.com/en-gb/guide/mac-help/mh21245/mac)

If so, you might be able to access some crash reports and submit them with your bug report (they should be included with sysdiagnose). Inspecting those reports may give you a clue as to what is causing your Mac to crash on login.

there are too many log files, still not able to understand what's preventing it to complete the login of the user; is it possibile that the beta 2 setup didn't complete, i wasn't there during the setup, so maybe it's someway at the reboot but the setup wasn't finished;

another option is that there's somewhat during the login that stops the procedure, but i disabled LaunchAgents and LaunchDaemons with no luck... :-(
