You can zoom in on one of the project views, and select the entire project, and then on the modify tab click on filter and search for the .dwg file you want, uncheck all others, leave only the file you want to select, ok, and then delete

it seems that the dwg is too small or too far from the rest of the project, you need to check why it is not seeing, if it is the insertion point or scale, or even the Autocad georeferencing / coordinates is correct com os do Revit.
There is an old post that talks about this with solutions with a Add-in, dynamo, etc, you can also try it.
