To everyone asking about the beta it is very subjective as to if you will even be able to download it. Even if you can it is a beta not ready for prime time. Unless you are willing to put up with bugs and report them I wouldn't download it. I would wait for the fully tested version. It will come when it's ready.
UserGc240anGiz. Clear all temp files and restart your phone. You could try restoring your phone. Android 10 is beta it might be a bug you have to live with. Make sure you fill out a bug report. If it is a bug hopefully it will be fixed in the next beta. Let us know if anything helps
