Problem with making a biome in MCreator 2025.2

So... I'm working on a addon mod with a 1.20.1 generator (so i could use the mods that you need to use when playing it), though i'm having some troubles making a biome for the mod due to it prob having issues with the 2025.2 Biome generator. Can anyone help me with helping me with this?

Plugins that might brought this error (dunno which generator i downloaded so i'm linking the first result i saw):

https://mcreator.net/plugin/120166/minecraft-forge-1201-generator

 

the error:

"One or more of your main mod files did not compile properly"

If you’re on 2025.2 still you’re using an old version of this plugin, which may be bugged. Is there any soecific reason for not updating to 2925.3 with a newer version of that plugin? Also, maybe a full log and/or workspace file may help to troubleshoot this.
