Answer 1

This is a Kotlin bug, you can vote and watch it for updates: https://youtrack.jetbrains.com/issue/KT-36253. A workaround is to kill the running Java processes.

Answer 2

I have this problem almost every build (Android Studio stable + Artic Fox).

Manual Solution (try this first, if it works continue)

Task manager > Processes > End "OpenJDK Platform Library" tasks (sometimes it's standalone, sometimes it's under "Android Studio")

OR

Task manager > Details > End "java.exe" tasks

Automated Solution

1. Create a new end-java.bat file
2. Content of .bat file: taskkill /f /IM java.exe
3. Right click end-java.bat file > create shortcut
4. Right click the shortcut > properties
5. Add shortcut key (e.g. ALT + CTRL + 1)
6. ALT + CTRL + 1 will now fix the issue
