I have a Dell Latitude 5590 with an Intel Core i3-7130U, and it's currently running Windows 11 Pro 21H2. I created a bootable Windows 11 USB using Microsoft's Media Creation Tool, but when I launch setup.exe from the USB, Windows says the processor isn't supported. I'm worried that booting from the USB might cause problems. Why is this happening, especially since Dell says this laptop supports Windows 11?

A tool such as Rufus can create installation media that bypasses the CPU, TPM, and other Windows 11 checks. That may let you reinstall, but it doesn’t change the fact that the processor is unsupported, so the same issue could come back during later upgrades or updates.
If you’re trying to restore the laptop to its factory software, use Dell’s official OS Recovery Tool rather than a generic Windows installer. Otherwise, Windows 10 is the more straightforward supported choice for this hardware.
The existing installation was probably made using a hardware-requirement bypass. The i3-7130U is a 7th-generation processor, while Microsoft’s normal Windows 11 support generally starts with Intel 8th-generation CPUs and newer. Dell may list the laptop as compatible based on the model or its supported operating systems, but that doesn’t necessarily mean every CPU configuration meets Microsoft’s requirements. You can force the upgrade again, but unsupported hardware may have trouble with future updates. Staying on Windows 10, with the appropriate extended-support option if needed, is the safer supported route.
So Dell’s Windows 11 compatibility listing doesn’t guarantee that my specific processor is officially supported?
