when ever i spawn in a register (same ones he made in the second video) they have a random value which wouldn't be an issue but if the random value is a 0 then it wont let me write data to the variable and anytime i use a chip which contains registers its randomly generates meaning i have to respawn the chip upwards of 100 times

TL;DR - working as intended.

In real life, latches and flipflops start in an unknown state. In the simulation *some* style of latches and flip-flops (those built on cross-NOR and cross-NAND gates) also start in an unknown state. Within the simulation AND-NOT-OR style latches start in a known state. There's a bit more nuance to it, but that's the gist.

Just like in real life, you need some sort of asynchronous Clear signal during your Reset cycle to get the register to initialize to zero.
