    I tryed as you commented. I'm able to get to the terrain with all its materials and look as is should be. But Unity keeps crashing when I restart it.

    So we just found a fix for the landscape with custom material crash.

    Test: Go to your terrain->settings and try changing your custom material and it'll crash.

    Fix: First change "Material" from "Custom" to "Built In Standard".
    Now change it back from "Built In Standard" to "Custom".
    Set your material to whatever you want and it works. Save and your project will reload fine without crashes.

    Having the exact same problem. Thanks for the tip about closing the scene and game tabs and loading that way.

    If I open the scene in editor with scene tab and game tab closed, loading is compled without crash.
