Unknown Cook Failure after migrating to 5.5

Ended up solving the problem. I went through each and every folder validating until I found a warning saying the lights had no Mipmap levels and were related to the VirtualTexture0 errors. Turns out I had some lights in one of my levels that needed to be rebuilt. I ended up just rebuilding the lighting for the entire level and it seemed to fix it. Really wish UE would’ve told me what the log was referencing :confused:
