Raspberries in general are very susceptible to root rot.. Here is some information on root rot affecting raspberry from the Pacific Northwest Plant Disease handbook - https://pnwhandbooks.org/plantdisease/host-disease/raspberry-rubus-spp-root-rot. It includes some recommended cultural controls.
If you choose to plant raspberry in an area that has had root rot, ensure that any drainage issues have been addressed, and look for a raspberry cultivar that is resistant to root rot. Check out this chart - https://pnwhandbooks.org/plantdisease/cultivar-tables/raspberry-cultivar-susceptibility
This OSU Extension publication "Growing Blackberries in the Home Garden" indicates that most blackberry cultivars (like Marionberry) are tolerant of heavy soils and will not get root rot - https://extension.oregonstate.edu/catalog/pub/ec-1303-growing-blackberries-your-home-garden
