Unreal Studio Beta 4.22 Release

I can’t download unreal engine 4.22. There is no update or option to upgrade my unreal engine. I am still using unreal engine 4.20.3 version and can’t update to a newer version. Is it because of my hardware or software? For the information, I am using VGA Geforce MANLI 1080 Ti and windows 10 as OS. Please help, I want to try Unreal Engine Studio 4.22 ASAP. :((((
