How to fix an iPhone stuck in boot loop?

My phone ran into a bootloop, and I think it was because of an update I forgot to install. I went into recovery mode and followed all the necessary steps, but when it tried to update, it showed an error: "The iPhone could not be restored. An unknown error occurred (4013)."

boot loop issue and cant do anything so last night my phone suddenly turned off and went into a boot-loop and turned on the recovery screen. so I went to restore it using my macbook, at first i tried updating it as i thought that would work but I was met with error 4013, and decided to update my mac (it was running on Sonoma) and i tried it again and suddenly, when the bar was on the stripes / getting the software/update, the phone entered the boot-loop again and the bar reset. I tried this 4 more times before doing the restore option. same thing happened. sorry if it wasn’t explained well, have no idea what this is and is my first time encountering this. I am using a Iphone XR. Summary: iPhone XR went into boot loop and cant update restore and all options running out, already tried updating the macbook even.
