Hello! So i recently closed my project, took a small rest, and when i opened it again the engine crashed with this error: ![Captura de pantalla 2024-12-28 135544](https://d3kjluh73b9h9o.cloudfront.net/original/4X/2/2/1/2212e4bfd2784756c82ef6506666223dcc944367.png) I tried looking in the forums for a solve and i tried resetting the graphics card’s settings to default and restarting the pc but the engine still crashes. PC: - NVIDIA GTX 1050 Ti - 16GB RAM - Intel Core i5-9400F 2.90GHz - Unreal Engine 5.4.4 Windows 11 64-bits The engine always worked good for me, even with many instances of it opened so it shouldn’t be because of the performance. ---

try to delete UnrealEngine cache folder, then start your project. delete this folder: “C:\Users\ -Username-goes-here- \AppData\Local\UnrealEngine” ---

That text says really nothing. In the unreal page of the epic launcher, modify the installation to include the engine source and editor symbols for debugging. Then the crash log should give more information ---

bump, i tried deleting “DefaultEngine.ini” file and the project now opens in an empty level, the problem is that when i open any level that was created before the crashing started, the project crashes. Also, my project doesnt use lumen or ray tracing and uses very low poly meshes and low res textures. ---

update // bump, i found a solution which is copying one by one the all the assets from the content folder of the corrupted project to another brand new empty project. Doing this seemed to fix the problem as i only needed to fix some references and thats it. But when i closed the project one sec and opened it again, the same crash problem started again. ---
