STM32Cube updater downloading to repository folder

When booting up STM32Cube for the first time I get the error "A 'stm32Cube Updater' (or another 'STM32CubeMX') software is downloading to the repository folder Please wait for the download to complete and retry" 
However, no software is open/ downloading anything and I have waited 30 minutes. When trying to open up the MCU selector it is stuck loading on most buttons as well.
