I am unable to create a project, as when I extract the generated zip file from the Architectury Template Generator, it crashes as soon as I run the gradlew batch file. I am on windows, the error that I get is in the common\build.gradle file saying that the line two common rootProject.enabled_platforms.split(',') doesn't work. The specific error it gives is: No modloader with id. I am on Architect Plugin version 3.4.159 and Architectury Loom version 1.6.411, with minecraft version 1.21. I did choose yarn as the mappings, I didn't edit any of the code post-extraction of the zip. Any help would be appreciated.

Did you check any of the boxes for Neoforge or Fabric? That error sounds like you didn't enable any mod loaders, so it's trying to build without any enabled.

I didn't, I will try that, thank you for your help!

Thank you! That worked
