I’ve been working on a small project based on the player actor from the base FPS project. It contains little but a Matisse, an event and geometry. It was working fine and was playable until I closed the project and resumed a few hours later. I can still work on the project, but whenever I try and play it, it freezes up and eventually crashes. The blueprint compiles, I can export the project and run it externally, but I can’t play it within the viewfinder. Below is the error message it returns, I can supply the necessary logs as well.
