I assume that the file format list (bottom left of export dialog) is empty?
Go to Edit>Preferences>Folders>Plugins. This should list two directories, one being where Gimp is installed. Navigate to that directory with a file explorer. It should contain a bunch of executable files named file-<some image type>(file-png, file-jpeg...). Is it the case?
If this is true and Gimp still doesn't work, rename your Gimp profile and restart Gimp.
