i am making a project using vscode, and using react and springboot.

and is error message suddenly pops up, and bothers me.

Could not open cp_init generic class cache for initialization script ‘C:UsersdjwlsAppDataRoamingCodeUserworkspaceStorage5cb870b7bccc637bbe1a3f9df7c0c634Oracle.oracle-javauserdirvarcachegradlenb-tooling.gradle’ (C:Usersdjwls.gradlecaches8.6scripts4jbi8vk6y16d54n1snyxw6doj). BUG! exception in phase ‘semantic analysis’ in source unit ‘BuildScript‘ Unsupported class file major version 66

i think this may be caused by gradle.

but i don’t know the exact reason.

thank you for kind support:)

build. gradle

` plugins {
id ‘java’
id ‘org.springframework.boot’ version ‘3.2.4’

    apply plugin: 'java'
