What version of Java JDK do you have installed?
Install the 1.8 one mentioned in the error message.

Sorted out that problem, but got another one:

Error occurred during initialization of VM
Could not reserve enough space for 2097152KB object heap
6

Open a new topic about that please. But I remember multiple older posts about this error.

Solved everything, one not never try to run it within the integrated terminal of visual studio code
