(Android) Unity crashes on building process

Well after updating Unity 5 i modified a couple things such as scripting and updating GUI to UI system, but i’ve got a weird issue when i tried to build my game for android.

suddenly the editor crashes in the middle of the building process (exactly in "Building List of referenced assemblies" for scene 0)
and then the editor closes and bug reporter pops up.

Part of the editor log says something like:

“Unity.exe caused an Access Violation (0xc0000005)”

and that is all, i can’t build my game and i don’t have another computer to build it.

Thanks in advance

Just for who has the same problem, i solved the problem by changing the quality in unity (2019.4.32f)
