Hi @신웅 윤
Have you installed other versions of Office on your computer before? If yes, please make sure the previous one is uninstalled completely.
I suggest you perform an "online repair" for your Office.
Besides, it's recommended to check your Graphics card driver, for example, if your machine has an Intel integrated graphics card, you can try updating its driver or rolling back to an older version.
Change the default printer for a check.
Any updates, welcome to post back.
