Make sure to run the .exe, not the .jar. It runs with the appropriate Java version (11)
Well the thing is I was running the .jar because the .exe does not even launch, my system is in French so the error message might not be super useful to you, but this is what I get (censored my real name for obvious reasons):
Uhhh the image is not showing. It's an error message that doesn't let me copy/paste the text
Check the error.txt file, it'll be copy-pastable. I'd like to see it, since maybe I can fix a language bug.
Until I do, though, if you get Java 11, you should be able to run the .jar.
