One or more of my main mod files did not compile properly

The popup claims it can solve the issue by regenerating the mod's code, but that does not work. I have no locked mod elements, which it says is the other reason this can happen.
I got this issue after updating mcreator today. This is what it outputs into the console, though I cut out some of it so it lets me post it here:

I don't know how to run the project with any commands.
