Problem with launching the launcher to check the mod

I'm sorry if something is unclear, as I'm writing through a translator.
Even on an empty project, the test launcher doesn't start, it first says "Run Build" and then "gradle is not active," and I can't create a mod either.
 

Here's what comes out in the console:
 

Build info: MCreator 2024.3.42716, forge-1.20.1, 64-bit, 7971 MB, Windows 11, JVM 21.0.4, JAVA_HOME: C:\Program Files\Pylo\MCreator\jdk, started on: 2026-01-02-11:54:31
Here's what comes out in the console:
FAILURE: Build failed with an exception.
