Hello, sorry that's distressing; however, it looks like the phone can be fixed with your data on it. :)
You already tried this:
long power press 60+ seconds
This forces the phone off no matter what then you must have turned it back on.
I think the screen needs to be replaced. The new screen probably comes with a new fingerprint scanner and the repair shop or you can calibrate it even with GOS installed on it I am pretty sure.
To test this for sure, you can force the phone off again (long press the power button 90 seconds to be sure it's off). Now plug in a phone charger and/or try a wireless charger. See if the screen turns on while the phone is shutdown. The screen should turn on no matter what software issues that could possibly be present.
1lovel1fe On my mac connecting it also vibrates and my mac asks to allow it, but from there, nothing...
I think you mean you can't see any files on the phone?
The phone probably requires you to enable file transfer on the phone.
There's a system setting called "usb controlled by" and I think the default is "this phone." You'd have to look at the phone's notifications for "usb connection" to enable picture or file transfer.
