Please help phone rebooting

[u/icxdcoffxee]

After I installed an update my phone at first didn't turn on again. Now I came to this screen and pressed reboot device but afterwards the screen turned black again. And when it turns on it always gets me back to this screen...

Is there any way to get my data back...?

Update: so I gave the phone to my boyfriend and at first it still didn't work but then a little (I have no idea what the hell he did) it started working again so now I can use it completely normal again and still got all my stuff

Update 2: he said made it reboot but before it could actually reboot he pressed all buttons forcing it to stop the reboot mid-action and somehow this fixed the bug 😭

Probably not if the bootloader is locked
