React-Native app suddenly stuck on White Screen when starting app

I've been searching for the solution to my problem, but can't find any answer that works and includes my specific error message.

Can any of you help me solve this issue and also teach me where to look to find the root cause of similar issues myself in the future?

The error message shown in console.log (after running yarn start --reset-cache and starting app) is:

[Wed Oct 28 2020 23:17:34.976]  BUNDLE  ./index.js

[Wed Oct 28 2020 23:17:40.424]  ERROR    Invariant Violation: Module AppRegistry is not a registered callable module (calling runApplication)

Below I have included the Logcat from Android Studio.

Thanks in advance. I really appreciate you guys/girls taking time to help other developers out and hope to repay by helping others out with my knowledge and experience...

EDIT: running gradle clean results in the following error:

FAILURE: Build failed with exception.

* Where:
Build file '/home/MyProject/node_modules/@react-native-community/datetimepicker/android/build.gradle' line: 1

- What went wrong:
A problem occurred evaluating project ':@react-native-community_datetimepicker'.
> Failed to apply plugin [id 'com.android.internal.version-check']
   > Minimum supported Gradle version is 6.5. Current version is 4.4.1. If using the gradle wrapper, try editing the distributionUrl in /home/MyProject/android/gradle/wrapper/gradle-wrapper.properties to gradle-6.5-all.zip
