4.26 shipping build crash

Hi, I’ve been running into this crash on my shipping builds. The error happens at runtime during the game and I believe its related to the AI spawning. Any help would be appreciated.

Greetings @ZoMbIeS_746

Welcome to the Unreal Engine Community Forum! I’d be happy to look into this with you. Does this issue happen if you try swapping to DirectX 11? (Assuming you’re running 12) Also, the VCRUNTIME140 caught my curiosity. I’d also ensure you have all of your Microsoft Visual C++ Redistributables installed. (A Google search on the VCRUNTIME140 with Redistributables will give you some results on that from the Microsoft site I believe) Let me know what you find when trying that.
