Hello @copilottry01,
can you create a reproduction repository?
Kotlin is not used in the plugin, so I will have a hard time understanding your issue without your context.

After updating many tries. I explicitly deleted .idea, .gradle, capacitor-cordova-android-plugins under the root android folder for no reason. and then it ran smoothly. IDK where was the problem. but it's no more. may be something wrong with the plugins.
But now it's working.

Thankyou.
