I too am having the same issue with my Cura 4.9. I have dragged and dropped, opened via the file menu and get the same message: "Failed to load <file path>.stl. The file could be corrupt, inaccessible or it did not contain any models." I have the older version of Cura on my other computer and it works just fine. The Ubuntu new version does not. I also did click on a .stl file and went through the properties and chose the "Unimaker Cura" optin. The program started opening with the loading items then failed with the above message. The same one worked just fine on the other older version on my other machine.
