If I have a Corona Outline Material in the material override slot it disables camera clipping and my entire interactive render is black. If I swap that material for a normal Physical material without changing anything else, the clipping works

Same thing
This is fixed in the newest Preview build and will also be a part of the upcoming Corona 14 release: https://forum.corona-renderer.com/ Chaos Corona 14 for 3ds Max - Previews (Daily Builds) Changelog #msg235216
Fixed outline material when used with camera clipping.
