can't read bootable usb on Dell Latitude 5430

Today I bought a

, and it came with Windows 11 already installed. So, I downloaded Linux Mint from the official website, made a bootable USB, and tested it on my old laptop; the USB worked fine. When I inserted it into the new Dell and tried to install Linux Mint, I encountered a problem with the SSD drive's BitLocker encryption midway through the installation. I canceled the installation and created an extra partition on Windows 11, then turned off BitLocker encryption. Now, when I try to boot from the USB stick, I get this message (check the pictures). I've tried using another USB stick, but encountered the same issue. I also attempted to disable Dell Safe Boot through the BIOS, but the problem persists. Could someone please help? Thanks.
