Export light remains at 0% and UE5 no longer works

[MaReLeToF]

Why is it that when I try to create light, the exported light percentage remains at 0% and Unreal Engine stops working? I’m using UE5 and it was working fine until I started creating a new level

Hey there @MaReLeToF! Welcome to the community! What do you mean by exporting lights? Are you referencing building the lights? If building lighting remains stuck at 0% there could be a number of issues.

However, often this is solved by deleting and regenerating the saved folder as referenced in this thread:

Building lighting stuck at 0%

Hello, I just created a new project, an empty project. I placed directional light and sky light. I created a standart 2x2 landscape.I pressed build and it got stuck at: Building lighting 0%. I tried it again a couple times but it didn’t work. I restarted my pc and deleted the project, I did the exact same things and it got stuck again. Please help me. Greetings Robin
