Npx cap run android couldn't configure root project android

Issue

I've been trying for hours now. I went through the error text, tried changing gradle versions, downloaded different versions of java sdk, cleaned the project, rebuilt the project. Nothing seems to work. It's pretty new ionic+vue project, so the versions are fresh, android studio version is up to date.

App is working when started with android studio on both virtual and physical device. I just really want to use npx cap run android.

Here's the error:

PS C:\custom\dev\ionic\app> npx cap run android --scan
