LNK 2019 unresolved external symbol... Dll missing?

Project was fine last night but after trying to launch today my project says it can’t compile and that some dll is missing.

VB errors:

No clue what any of this means… please help.

UPDATE: Part of the problem was a file I had made which after deleting fixed some errors.

I now only get 1 error now.

That specific error does not tell us anything useful. If I recall correctly LNK2019 usually means you have declared a method signature in a header file but did not create its implementation (either inlined or in a CPP file).

Provide the contents of your output log. You can see this by doing View > Output.

What about MSB3073 is it just some generic error message

Just ended up copying my blueprints into a new project and everything works as before.

Lesson being don’t mess with C++ if you don’t know what you’re doing if you don’t want to break your project. =D
