I think you are somehow running dlls meant for hot reloading. Go to your Binaries folder in your project and delete all your binaries, then get some new ones rebuilt while the editor is closed. If you don’t compile code, grab the binaries from your source control or another programmer.
I just wanted to clarify that this particular problem is no longer an issue for you. If it’s okay with you I will be marking this post as resolved to focus support on the other post. If you feel these are separate problems you can reopen this and we will investigate both issues.
