iPhone XS Max stuck in bootloop, cannot get into recovery

This issue started with a message saying that my storage space was almost full. I open settings and check storage, the estimate size does not show up. I go to photos app to delete a few photos/videos. I select a bunch and hit on delete, the images do not delete and the phone reboots into the Apple Logo.

It's been stuck on the apple logo boot loop for a while now.

Unable to set the iPhone to recovery mode by holding VOL UP + VOL DOWN + Power Button for 10 seconds.

Plugging the iPhone into my Macbook does not show the device connected.

What should I do next?

iPhone Model - iPhone XS Max 256GB

iOS Version - 14.4

this honestly sounds like your device's drive got corrupted entirely. you'd be better to send it to Apple for repair, i don't think there's anything an end-user can do without voiding any warranties or whatnot at best, destroying the device accidentally at worst.
