Mac won't boot up past log on screen

Mac won't boot up past log on screen. I enter password. It sometimes boots to start screen but within 30 seconds reboots again back to log in or just turns off completely??

iMac 27″, macOS 12.6

Hoping you have a recovery partition.

Hold down the Command-R button at boot, select recovery.

If you get this far the Mac will boot into a 'safe place'.

From there look for DiskUtility and run it.
