Unity 3d Building navmesh exporting tiles takes too long . Help please

My problem is this. I baked the floor for the nav mesh agent. but he did not bake after almost 3 hours . It's been a very long time, but now it says exporting tile and still bakes. It used to go faster, what could be the reason please help

 

Benim sorunum şu . nav mesh agent için zemine bake yaptım . ancak neredeyse 3 saat geçmesine ragmen bake yapmadı . Çok uzun bir süre geçti ancak yine şuan exporting tile diyor ve hala bake ediyor . Eskiden daha hızlı geçiyordu sebebi ne olabilir lütfen yardım edin

 

I finally solved it. Friends, the problem was that the terrain or the ground was large. Try shrinking the floor!
