Can this problem be fixed?

I've just decompiled your code of OverworldBiomeBuilder.class. This implementation is not recommended:

@Mixin({OverworldBiomeBuilder.class})
public abstract class OverworldBiomeBuilderMixin {
    @Unique
    private final Climate.Parameter seagrassMeadowTemperature = Parameter.m_186822_(0.24F, 0.35F);
    @Unique
    private final Climate.Parameter seagrassMeadowContinentalness = Parameter.m_186822_(-0.355F, -0.17F);
    
    // ...
}

What you are supposed to do is:

@Mixin({OverworldBiomeBuilder.class})
public abstract class OverworldBiomeBuilderMixin {
    @Unique
    private Climate.Parameter seagrassMeadowTemperature;
    @Unique
    private Climate.Parameter seagrassMeadowContinentalness;
    
    @Inject(method="<init>", at = @At(value = "TAIL"))
    private void spawn$onConstruct(CallbackInfo ci) {
        this.seagrassMeadowTemperature = Parameter.m_186822_(0.24F, 0.35F);
        this.seagrassMeadowContinentalness = Parameter.m_186822_(-0.355F, -0.17F);
    }
    
    // ...
}

Noticed that you haven't uploaded your code yet, so I can't send a PR to this project. We're looking forward to seeing you fix it. @N1nn1
