Reset DerivedDataCache to Default location

Hi guys, so I went ahead changed the location of my DerivedDataCache. (EditorPreferences and picked a spot for local DDC.) But now I can’t get any of my 4.26 projects to load. I realize it probably just has to create a new 160gb of ddc but I thought it would just affect new files. Is there anyway to reset the location to the default one without opening the editor?

Any help would be greatly apricated, Thanks!
