Gradle sync is failing after I updated its version in Android Studio. On checking the IDE logs I can see the following entry

While looking at the relevant entity name
org/jetbrains/kotlin/kapt/idea/KaptGradleModelorg/jetbrains/kotlin/kapt/idea/KaptGradleModel
There seems to have possibly been some sort of an error while copy-pasting. To the best of my understanding this isn't something I've done.
The project in question doesn't use Kotlin at all and has no plugins or dependencies for it either. It does seem that the project was configured for Kotlin at some point in the past and subsequently altered to remove the configuration.
Edit: Originally suspecting that the issue was with Gradle version 4.10.1 that Android Studio Prompted the update to, I tried to manually update to version 4.10.2 which also didn't solve the problem.
Update: Reverting the project to version 4.6 also doesn't do anything.
For this, you have to connect your PC to the internet and you have to open your Android studio. After opening your project click on the Sync Project with Gradle files option. This will automatically download the new Gradle files and will fix the issue which is caused by the Gradle files.
Open your gradle. properties file in Android Studio. Restart Android Studio for your changes to take effect. Click Sync Project with Gradle Files to sync your project.
Following steps helps me -
Change the gradle version to 5.2.1
Upgrading the Kotlin plugin and restart Android Studio.
I found that the kotlin plugin was not checked under Settings / Plugins / Installed. Checking it and restarting the IDE solved the problem, without having to change Gradle version.
