Why do Tilemap collisions disappear on build?

Question

Unity

I built a map using TileMap, threw a TileMap Collision on an object with walls. Everything works in Unity, but when I build the project, the collisions with TIlemap disappear at the output. What could be the problem? Maybe some bug in the version of the unit or did I do something wrong?
Unity version 2021.1.3f1, building under Windows x86_64 using Mono
