RuntimeException: Failed to instantiate language adapter: kotlin

[christianm20358]

Hello,

I'm getting the following stack trace when trying to launch the debugger in vscode. I've put my environment info below, I'm new to both Java and Kotlin so it may be that there's an incompatibility there, I do get a message in vscode when in the KotlinAdapter.kt file that says FabricLauncherBase' is deprecated. Deprecated in Javakotlin(DEPRECATION)

I have not modified anything in the project, this error occurs after running genSources and vscode gradle commands, then attempting to run the auto-generated "Minecraft Client" debugger profile. Let me know if it's something happening on my end due to my setup, any guidance or direction for fixing this would be greatly appreciated.
