My Intel Macbook turns off when making a bootable USB. Then when turning on there's a black screen after logging in and sometimes it shows an error (in the picture) when trying to turn it on. When I managed to turn it on it gave me a "panic media boot" message.
The recovery mode doesn't work.
Is there any way to fix this?

If a simple reboot of your Mac doesn’t fix things, see if the problem still happens in Safe mode (press and hold the shift key down at startup). It can take much longer to safe boot (10 min) so be patient.
How to use safe mode on your Mac - Apple Support
Safe mode allows the computer to do cash purges and miscellaneous file maintenance and housekeeping, and is non-destructive to user data. It’s not a cure-all, but very often corrects weird software behavior. When you're in safe boot, the machine will not be at its best performance, especially with graphics, but that's expected.
Does the problem persist while in Safe mode?
Exit safe mode by restarting your Mac normally and re-evaluate the issue again.

What is the exact model of this Mac and version of macOS? You can get the exact model by entering the system serial number here:

Did you remove the USB stick from the Mac when rebooting? It is possible the USB stick has a hardware issue, or perhaps even the laptop's USB port has a hardware issue.
Disconnect all other external devices in case one of them is causing a problem.
