Suddenly noise/low resolution when opening project

Hello, I’m working on my first project in Unreal. I have worked on this for almost a month and had no weird problems until now. When I opened the project I see suddenly noise everywhere: textures, materials and shadows. I spent half a day looking to resolve it but to no avail. Quality settings are on high, never adjusted them. Anti-aliasing is set on TSR. In the beginning got this message about ‘Resizing virtual pools’ but I did NOT get a warning ‘red text’ about vram. I on epic forum to disable this setting: 'pool auto grow in editor" but I did help me. Any clues to what might have caused it? Appreciate it.

Edit: here is a screenshot
