Messed up big time MBP 9,2

Hello, I think it really messed up, I have 2012 MBP 9,2 thought I got everything setup to USB boot up sequoia, deleted my old OS, but when going to install sequoia from recovery it says error occured while preparing the install. But now I wiped out the old OS and can't go back into the computer to try and fix. Is there anything I can do to fix this? Thanks
