HELP WITH IMAC KERNEL PANIC ERROR :(

[OCD-FREAK]

i have an imac late 2015 with a 2tb fusion drive that started randomly giving kernel errors and once rebooted into the OSx Monterey it gives me an error saying "the disk you attached was not readable by this computer" and gives me 3 options: eject, initialize or ignore, when i chose initialize i was taken to disk utility that showed me apple ssd 128GB as unmounted and when i try to format, it keeps going and doesn't format.

 

thanks!
