Hot Reload Crashes Editor

After working for a while, it seems that hot reloading is crashing the editor. I change some code, build, and the editor crashes. I reopen the project build again and everything is fine. Once this starts, it’s build-> crash-> reopen-> build again-> build successful. As you can imagine, this is killing the iteration times and is very annoying. This has been happening two days in a row now, but I was able to work for several hours today before it started again. A reboot doesn’t seem to help. Any ideas?
