UnityPackage Error with NMecab

There was no problem with NMecab's part of speech on Unity's game screen, but if you run a file created by building it, you will get an error, perhaps because NMecab doesn't work well.
If there is any missing information, I will write additional information. Thank you.
Part of the error code.

TypeLoadException:Could not load type
