Hey @Sethrichardz, welcome to the Unreal Community!
The whole screen going black sounds like the graphics card crashing. What GPU do you use, and are your drivers up to date? Some GPUs log crashes, but you can also look for crash information in Event Viewer in Windows, sorting by System and Application by time may give some insight as to what is crashing.
I recommend updating your GPU drivers first, then rebooting Windows and seeing if that helps!
I hope this information helps, and good luck!
