iPhone reboots after 3 minutes if I go into unlock screen

Hi,

Recently I was using my iPhone to take some pictures during a rainy day when it suddenly shut down and started to go into a boot loop. It eventually managed to boot, and long story made short, the situation is now as follows:

• If I leave the iPhone as it is when it boots, i.e., without even going into the unlock screen (the one where you would input the unlock code), it remains on indefinitely
• If I even go into the unlock screen, it will turn off after 3 minutes
• After it turns off, it goes into a boot loop of variable duration, but eventually boots again

I had a lot of pictures (around 3000) without back up that I would like to save. On one of this times it booted, I confirmed that all the photos are still there. Even the camera is working fine. But since it will automatically reboot after 3 minutes, I don't get the chance to save them for example through the Photos app on my MacBook

At this point , my priority is to try to backup all the photos. Any suggestions on how to proceed would be greatly appreciated! I currently have the phone booted and without having gone into the unlock screen. It has been this way for 40 minutes now

I had a look at the Analytics data as well one of these times before it rebooted automatically, and there were panic-full messages. If I have a look at the timestamp of the panic-full messages, they indeed happen 3 minutes before it shuts off automatically every time. I managed to extract a couple of examples of the panic-full messages, in case these are useful, in ips format. These are quite large, but I can share them if required

Edit: please find here a screenshot of the 1st page of the panic-full message
