There's a strange problem when I try to save a document in InDesign. It doesn't happen every time but it's reoccuring and quite annoying. When I try to type something in the "save as" field, all the characters change as if Cthulhu has taken over the system. The only way to be able to save is to cancel and try again until it doesn't happen. This problem has only occured in the Adobe Indesign 2021 version.
