Having trouble saving a project in Audacity

I am using Windows 10 and my version of Audacity is 3.1.2.

I have a project due for school that I was just editing. I have managed to do most of the editing of it and just need to put my sound effects into it, but unfortunately for some reason, whenever I go to save or export the file the tabs to do this are grayed out. As are the tabs for start a new Audcity project, the close tab, among others. I am not sure what I am doing wrong. Other people have had this issue, but it does not appear to be the same type of issue as mine, as they were able to fix it right away. Thank you in advance for any help you can give me!
