iPhone XR Breaks Completely

About 2 years ago, I received my iPhone XR. About 6 months later, a weird screen anomaly occurred in the lower left corner, which looked like a screen burn in (this is my post about that: https://www.reddit.com/r/applehelp/comments/ehpl6h/iphone_xr_screen_burn/). For about a week or so now, my phone has been giving me „please clear up some storage“ notifications, which I ignored cause I didn’t really use my phone that much during lockdown, and thought 0.4gb left were enough for the phone to operate, given I have survived on much less storage left before. Suddenly today, whenever using an app, it crashed after doing a certain action. When browsing, it was entering a search term in google. In settings, it was when opening a menu option. Every app was bricked. So in panic, I shut down the device. Upon starting it again, it didn’t seem to boot back up. Now, it has been stuck in the boot up for 2 and a half hours. When trying to force shut down again, it wouldn’t do anything. I tried contacting support, however my warranty has expired. What am I going to do about the supposed death of my phone and the tons of photos? Please, I am devastated and don’t know what to do. Many thanks in advance.
