Opening new or existing maps crashes the ark dev kit

I was designing a map then the update came out adding aberration into the dev kit. now when I open my map or try and make a new one it crashes at 100% loading of the map. does anyone know how I can fix this?

Same for me crashes at 100% loading. No idea why.

i changed the size of the map and it worked again maybe try that if you want to consider making a new map
