Every single project and UE version on my computer is broken

My bad for the late reply, but no, no issues with crashes and no logs or anything. And there really isn’t any elaborate sequence of steps that’s causing these little bugs. If I open my project, without doing anything, the problems are already present; for example switching the view to nanite triangles, all that happens is the lit view gets quite a bit darker, ambient occlusion doesn’t work despite following all the steps in both material set-up and AO enabling, if I move a spline point on a PCG graph for my landscape, the plants don’t update, if I put a comment box around a set of nodes on the PCG graph, the comment boxes will be gone the next time I open the project, etc.

I also had the Dash plugin on a couple versions (I’ve since lost them because I un-installed a couple versions of UE and re-installed them to see if that would fix these issues, and I never re-installed Dash), but when I had Dash installed it was experiencing a bunch of different problems that nobody in any Dash tutorials ever had to deal with, so it seems I was the only one dealing with the kinds of bugs I was dealing with. And like I mentioned, I didn’t have to perform any steps prior to any of these issues arising, they’re present immediately after opening the project.
