Spring Boot stop immediately after start up

Hi there, 

I am encountering an issue when running a Spring Boot  2 + Kotlin. 

IntelliJ Version

IntelliJ IDEA 2020.1.2 (Ultimate Edition)
Build #IU-201.7846.76, built on May 31, 2020
Licensed to ATB Financial / Cheng Xu
Subscription is active until October 18, 2020
Runtime version: 11.0.7+10-b765.53 x86_64
VM: OpenJDK 64-Bit Server VM by JetBrains s.r.o.
macOS 10.15.5

Memory: 1981M

Non-Bundled Plugins: EclipseCodeFormatter, JMeter plugin, Lombook Plugin, PMDPlugin, com.github.kisstkondoros.codemetrics, org.intellij.RegexpTester, Dart, io.flutter, org.jetbrains.kotlin, MetricsReloaded

Symptom: 

The project runs fine in command line via `gradle bootRun`. However, it stops immediately after start up if I ran it from IntelliJ.

```

What have I tried? 

- Define a controller

- Include `implementation("org.springframework.boot:spring-boot-starter-web")` 

But it doesn't prevent the issue from happening.

Please help. Thanks!
