"Navmesh needs to be rebuit" error when level change in android device

Hello everyone,
I’m developing a project more than 6 months. But I have a problem. Navmesh is working without any issues in editor. But when I plugged my a8+ and launch level from editor then change level , navmesh isn’t working and my ai doesn’t move.

I’m constantly searching a solution for this issue. But I cannot find one. How can I solve it?
