Try installing manually without Toolbox. If the issue persists, file a bug per https://developer.android.com/studio/report-bugs.html.
manual installation is not working as well

The fix is called out here https://developer.android.com/studio/preview/features#4.1-ki-missing-kotlin-plugin
Basically go delete the kotlin directory from the plugins directory in the imported config.
I had no Kotlin directory in mentioned paths.
But figured out fix - open /home/$USERNAME/.AndroidStudio4.0/config/disabled_plugins.txt and remove line with org.jetbrains.*
Mr. Mark, can you please tell me how to delete kotlin directory. I am not able to find it anywhere in the files explorer.
Please reply.
Go to your Android installation folder
then go to plugins
I deleted the kotlin directory but still my problem is not solved. It still shows the same.
Also there is no file named disabled_plugins.txt in my files.
Please can anyone help me what to do now.
Hello,
Please check "C:\Users\<USER_NAME>\AppData\Roaming\" and "C:\Users\<USER_NAME>\AppData\Local" folders. Also you may try to clean all used folders (https://intellij-support.jetbrains.com/hc/en-us/articles/206544519) and reinstall IDE from the scratch.
