1, you may not be able to download the latest version, so you can't log in or open it. There is only one solution, that is, download the latest version.

2. If there is something wrong with the downloaded app itself and it can't be opened, there is only one solution, that is, uninstall the app and download a new one, and then open it after the installation is successful.

If it still can't be opened, there may be a bug in the system. Just wait patiently for the system to fix bugs.
