I cant be sure on what’s happening, but i have a quick solution. Open the task manager, search in process for the Uniy process and Roght Click it, then click on Set Affinity. Uncheck the “All Cores” box, and just check core 2-3, or whatever you want. Wait like 5 mins for it to accustomize. Then switch back to All Cores… it should be fine.
