Why is my project crashing when I try to open it after a change in project settings?

Hi there, I’m currently working on my first project in Unreal and have recently run into an issue where every time I try to open my project, the crash report pops up instead. This happened right after I changed a few settings under Rendering → Virtual Textures. I changed the tile size from 128 to 2048 and I think I disabled Zlib compression. After having restarted Unreal so that the changes are implemented, I now run into a crash report when I try to open my project. I would truly appreciate any help!

This is what the Crash Reporter shows:

Unhandled Exception: EXCEPTION_ACCESS_VIOLATION writing address 0x0000000000000010

UE4Editor_Core

UE4Editor_TextureCompressor

UE4Editor_Engine

UE4Editor_Core

kernel32

ntdll

I’m pretty sure you can reset the settings, by tinkering with the engine ini files:

But it looks like your PC can’t handle those settings. I have no idea if they are extreme of not BTW…

EDIT: To be clear, it will be quite obvious when you find the settings you are looking for, don’t just randomly tweak things.

Thankfully, I managed to recover most of the project. My original issue that I was attempting to solve was an odd pixelation occuring in my virtual textures. Here’s a screenshot of what I’m referring to. The right side is how the original diffuse looks like and the left side is how it looks in scene. Any ideas on how to go about fixing this? Would appreciate any help.
