"layout_constraintBottom_totopOf" not found

On rebuilding the project,I get an error like this

AGPBI: {"kind":"error","text":"error: attribute layout_constraintBottom_totopOf (aka com.example.seve:layout_constraintBottom_totopOf) not found.","sources":[{"file":"C:\\Users\\hack1\\IntelliJIDEAProjects\\Seve\\app\\src\\main\\res\\layout\\layout_screen.xml","position":{"startLine":10}}],"original":"","tool":"AAPT"}

I went to layout_screen.xml and saw nothing useful on line 10 of the xml file. If anyone could help me what "startLine":10actually mean.It would be of great use.

Here is my layout_screen.xml

I expect the project to build successfully but i am not able to find the error on line 10 or maybe i am looking on the wrong line.
