Failing to recompile when I want to do anything like export, test enviroment and tells me to regenerate the code.

Status
Outdated
Issue description

When i am making/editing a mod, after a bit of time it will say that the mod failed torecompile and tells me to regenerate the code. So i click the button to regenerate the code and when i do that the same process repeats, when i ignore it, the box next to "idle" goes red. when i try to export or run client( when i ignore it) the process will happen again, but before the pop up telling me to regenerate the code, another pop up will appear saying that it failed to recompile the mod (elements of the mod) please can you help me fix this as i really enjoy making mods with mcreator and i am trying to start making a more biomes mod

Thanks,
