I tried to check all the version compatibility but keep facing the same error. I asked a similar question earlier but i didn't provide all the affected files. Hope these files will help debug the issue. I've been stuck for days.

Please don't post such walls of text to the channel, especially on mobile it makes it hard to follow the channel. Better post a short message and add lengthy details in the thread. Regarding the issue, from a cursory look I'd say you include the

app

project in two builds. Never ever ever ever ever ever do that. One project should always only included in exactly one build. If it is need on another build too, three whole build should be included using composite builds instead. This is also part of your problem. In one of the build including that project you define

google()

as plugin repository, in the other you don't. So you try to execute the build where you didn't and there the AGP then cannot be located.
