Description of the bug

Since I've updated to IntelliJ 2023.1 (and subsequently the plugin), adding breakpoints into mixins no longer works.

I have this simple mixin:

@Mixin(ArrowInfiniteEnchantment.class)
public abstract class ArrowInfiniteEnchantmentMixin {
	@Inject(at = @At("RETURN"), method = "getMinCost", cancellable = true)
	private void onGetMinCost(int lvl, CallbackInfoReturnable<Integer> cir) {
		cir.setReturnValue(lvl * 12);
	}

	@Inject(at = @At("RETURN"), method = "getMaxCost", cancellable = true)
	private void onGetMaxCost(int lvl, CallbackInfoReturnable<Integer> cir) {
		cir.setReturnValue(65);
	}
}

But when I try to set the breakpoint to cir.setReturnValue(lvl * 12); I get

The error doesn't pop out if the breakpoint is set when debugging is stopped, but it still doesn't work

This works fine on my end, same IDEA and plugin version.

Have you tried a gradle clean build ? Or invalidating caches after the IDE update ?
