Imac is suddenly stuck in boot loop

Hello all 1st time here. I have an Imac late 2015 with the intel processor. I came home and it was stuck on the apple screen with the progress bar at about 60%. It stayed like this for over an hour then started the process over again. I turned off the computer and booted into recovery mode and tried to repair the disc in utility. It ran for about 30-45 minutes then stated it had failed to fix the problem. I then tried to "Restore from Time Machine" which also did not work. I then tried to "Reinstall macOS Monterey". This started out saying it would take 2hrs 18min then the time started to increase over time. After about 30 minutes the install time had climbed to over 139hrs. Please help. I have information that I need on that computer, especially from the notepad. I took a few screenshots of the process.
