UE4 doesn't save Build Data

So, I build my light, I save the project. close and reopen it, and it tells me that nearly verything has to be rebuild.

It works in a new map in the project folder
I already tried to let unreal create a new FirstPersonExampleMap_BuiltData.uasset by deleteing the old one and let unreal write a new one via bake, but the issue is still there. Any ideas?

Hello! Build Data is generated by UE from other assets (maps, BPs, etc), so strictly speaking UE can build it at any time, that’s why it is not saved, although building lights can eat some time ))

I have problem. Any solution? (UE 4.26.2)
