So the main problem seemed to be that rsp would go out of alignment every time I pushed to it, the solution was simple enough, add rsp, 8 fixed the code. fixed assembly:

default rel
extern ExitProcess

section .text
global _start
_start:
    and rsp, 0xFFFFFFFFFFFFFFF0

    mov rax, 32
    push rax
    push QWORD [rsp+0]
    add rsp, 8

    pop rcx
    mov ecx, ecx
    call ExitProcess

Basically I had to align the stack pointer after every push
