Expert Response
https://extension.umn.edu/plant-diseases/oak-wilt-minnesota. There are a host of other diseases and insects that can cause this as well. I would recommend contacting a local tree care company and requesting an arborist consultation. The arborist can evaluate, diagnose and let you know the needed next steps.
