(4.17.1) Editor Crashes when I click paint in Landscape Mode

I’ve recreated the landscape in a new project with the same result. It seems to only crash on landscapes with layers in the material as soon as I click the Paint button under the Landscape mode. The crash log mentioned the skylight, so I deleted it with the same result as well. It crashes every single time.

Here is the crash log:
