Slow Migration and Level Loading?

I’m a beginner trying to complete the First Hour in Unreal Tutorial, but I’ve been stopped for 10+ minutes at a time for migrations to complete or for opening the demo levels. I know the files are a few GBs in size but I have a system with a i7 12700k CPU and an RTX 3080 GPU, so this really shouldn’t be taking that long. Does anyone have an idea why this is happening?
