iPhone XS Max 512GB Slow/Shutting Down

I have an iPhone XS Max 512 Gb that is going extremely slow and shutting itself down constantly.
Not sure what’s going on with it but it has a lot of personal stuff on it that is not backed up, like crypto wallets photos and person text messages that I need for a court related issue. I was wondering if there was a way I could send it to you and see if you can work your magic and get it working again.

check with ipad rehab good sir they are quite good at these types of things
