Error notification when creating new termbase (file could not be found)

Hello! I am trying to create a new termbase and when I klick finish, the program keeps showing the following error: "Die angegebene Datei konnte nicht gefunden werden" (The file could not be found). I have repeated the process several times with step-by-step instructions since I am doing the online course Trados Studio Level 1 (Module 7 - working with termbases). Although I am doing the exact same thing as described in the video, the notification keeps showing up. Can someone help? I am working with Trados Studio 2022 Professional. Thanks in advance!
