Weird corrupted text with ⦸ symbol in the middle.

Im trying to make offline installer for macOS Mojave on my pc from this guide, but when I trying to launch it, after some loading it kinda brokes. (Logs don't generate on pendrive btw but I'm not sure if I close it correctly)

Here is a photo.

My specs:
CPU: i5-3570k
GPU: GTX 970
Motherboard: ASRock Z77 Extreme 4
