Unreal Engine 5.1 Crashes Opening a Map, Hides Blueprint Actors

I upgraded from a 4.27 project to 5.0, everything worked fine, the main problem with 5.0 was the terrible performance, sudden lag spikes, and ultimately the server travel command didn’t work. I saw that this was fixed in 5.1, so I decided to update from 5.0 to 5.1. However, in this version the performance is even worse, although in theory the server travel problem has been solved. However, I can’t test it because it doesn’t even open a level after I run ‘open’ in the console. I’m trying to adjust settings to see if it solves the problem, but definitely 5.0 and beyond is causing a endless amount of problems.
