Z80 Assembler, 50 bytes

org 256
ld de,m
ld c,9
jp 5
m:db"Hello, world!\r$"

With assembler there's usually the problem which machine or operating system the program is for. I've chosen CP/M here as it runs on a variety of different machines with a Z80 processor.

CP/M programs start at address 0x100, but the decimal representation 256 is shorter.

The program loads the address of the $-terminated string into the D & E register pair, then the number of the print text subroutine (9) into the C register, and jumps to the BDOS entry. It uses the RETurn of that routine to end itself, instead of CALLing the BDOS and needing an own RET instruction in the program.

main(){puts("Hello, World!");}

This is using GNU C extensions. GNU C allows main() over int main(), ss well as using puts without including stdio.h.

They kept saying that jq is the language of September 2021. Still surprised no one even made a Hello, World! on it.
