Hourglass in corner?

[Dksz]

Hello everyone,
I am trying to add some programs to my HP Prime, but every time I plug it into my computer, I get a loading/hourglass symbol in the corner. I have made sure that I have the most recent version of the connectivity kit, I am using the stock cable(and I have tried others), I have tried on both Mac and Windows (both 10 and 11), I have factory reset the calculator, and tried USB 2 and 3. I don't know what else to do. If any one has any suggestions, please let me know.
