"Object reference not set" error JUST in build

Hi there! Here my case
I have a scene. It works well in editor and build. After adding some UI elements, adjusting referenses and save i got 4 errors like "Could not extract GUID in text file ... line 225589."
On this lines i see
"{fileID: 2, guid: 00000000000000000000000000000000, type: 0}"
I changed it to
{fileID: 0}
Then save. And it's still works in editor. But in build i got bunch of errors like
" E/Icon: Unable to load resource 0x00000000 from pkg="
"Object reference not set to an instance of an object" in places when it's 100% present and works in Editor well (and not changing in code in IF ANDROID sections).
"Error deserializing reauth settings response from device: org.json.JSONException: No value for recovery_url"
And so on. And that all after only scene saving.

 

I'm also having this issue
