Engine keeps crashing when managing World Outliner

Hi everyone, the problem is simple and you probably got it from the title. But to provide a bit more details: the engine keeps crashing when I manage folders in the World Outliner. It’s not systematic, meaning it happens randomly, but so often that I simply can’t work anymore. The engine simply freezes, but it doesn’t make windows or my computer crash. I just have to End Task and reboot the Engine, just to have it crash again 5 minutes later. It never did that before. My project crashes when opened with both 4.22.3 and 4.23.1. Thanks in advance!
