IntelliJ 的问题 - 无法运行简单的 Spring 应用程序

Question

I don't know what is wrong but I created a new Spring Application and tried to run it but I always get this error:

Error:Internal error: (java.lang.IllegalAccessError) class com.intellij.util.io.FileChannelUtil (in unnamed module @0x5db45159) cannot access class sun.nio.ch.FileChannelImpl (in module java.base) because module java.base does not export sun.nio.ch to unnamed module @0x5db45159

try updating your Intellij IDE to the latest version. Worked for me.
