Bug Unity possibly destroying my scene on reload, leading to null errors.

Hello when I try to hot-reload, unity has started throwing null errors for every method that tries to run. A tool I have called Fast Script Reload says that unity is destroying either my manager scene or its own manager system on reload because of something to do with static variables? Either way, the problem persists with or without the tool installed. I'm not sure I understand it, but here's the error.

 

So are you triggering a domain reload during play mode? Your project has to be super specifically set up for this to work without issues happening, and 99% of projects are not.

 

Oh? I am actually. It was working before, but recently it just stopped. I guess I added something?
