Gradle Build Errors in Android Studio

It's my first time using Android Studio, or developing an Android app in general, so I'm sorry if it's an obvious error.
When I try to build my app I get errors, as seen below.
Information:Gradle tasks [:app:generateDebugSources, :app:generateDebugAndroidTestSources, :app:mockableAndroidJar, :app:compileDebugAndroidTestSources, :app:compileDebugUnitTestSources, :app:compileDebugSources]
H:\Stage_3\CEG3799_Individual_Research_Project\App\CEG3799\app\build\intermediates\manifests\full\debug\AndroidManifest.xml
Error:(36) error: unknown element <activity> found.

The debug file it is referring to is https://pastebin.com/Yyc1wGDL. The main AndroidManifest.xml file is https://pastebin.com/kj978xd4. If I try and move my <activity> to inside my <application>, I get the following error instead.
Error:Execution failed for task ':app:processDebugManifest'.
> Manifest merger failed with multiple errors, see logs
This is the console / logs that I can find https://pastebin.com/pT1m0GLZ.
The build.gradle is at https://pastebin.com/6r5ys8Fi
Can anyone help advise me how to get this working? Thank you in advance

When you move <activity> inside <application> you'll have two <activity> tags with the same android:name="uk.ac.ncl.b5027438.CEG3799.MainActivity". delete one of these tags

Move the
<activity
android:name="uk.ac.ncl.b5027438.CEG3799.MainActivity"
android:configChanges="screenSize|orientation" />
inside the <application> node

you can solve this by separating into smaller bucket of task

i had issues, when i ran assembleDebug and test together in Jenkins as a single task

Information:Gradle tasks [:app:assembleDebug]
To run dex in process, the Gradle daemon needs a larger heap. It
currently has approximately 910 MB. For faster builds, increase the
maximum heap size for the Gradle daemon to more than 2048 MB. To do
this set org.gradle.jvmargs=-Xmx2048M in the project
gradle.properties. For more information see
