3
Look for options to rebuild, re-register, or re-initialize the language model. This process typically involves deleting the existing (potentially corrupted) model and recreating it from source files or database structures.
4
Execute the rebuild/re-registration process. This may be a time-consuming operation and might require specific system privileges.
5
