See in About the real JDK version used by IntelliJ IDEA. It's probably wrong is not not the bundled one, refer to https://intellij-support.jetbrains.com/hc/articles/206544879.

Run from the terminal: https://intellij-support.jetbrains.com/hc/en-us/articles/360011901879-How-to-start-IDE-from-the-command-line .

Set this before running:

export IDEA_LAUNCHER_DEBUG=true

Provide the output from the Terminal.

It's possible that you override the default with an env variable or some option/property forcing you to run on 1.8 instead of 11, see Help | Edit Custom VM Options and Help | Edit Custom Properties.
