Random Artifacts When Rendering

I'm getting weird artifacts but only after rendering. They aren't showing up in the preview window before rendering when viewing the video, but they do show if I pause the preview. I've tried hardware and software rendering as well as different formats (H.264/H.265)

Specs:

Windows 11 Pro

Intel Core i7-6700K

EVGA GeForce GTX 1060

48GB DDR4

Samsung 860 QVO

Western Digital Gold 6TB

Tried in Premiere Pro Beta 24.3.0.38 and Premiere Pro 2024 24.1.0.85
