I have MacBook Pro (13-inch, 2016, Touch ID model), and I've been on macOS 10.15 Catalina developer beta since June without any issues. However, since updating to the latest beta, I have several major issues:
- Item dragging is not working. I've tried three-finger drag in Finder on built-in trackpad and using Logitech MX Master mouse. It simply selects the file and doesn't move the file as I move the mouse cursor.
- Safari hangs very often, especially when editing text. I have to Force Quit it every couple minutes. I've tried disabling all extensions and clearing Caches from Develop menu. (FWIW Chrome works perfectly good).
- Same in Mail app, when I try add a new mail account. When I edit texts in Mail Preferences window, the app hangs.
- I can't download any new apps from the Mac App Store. It starts downloading process but nothing happens, stuck at 0% progress.
It looks like all these problems appeared after I updated to beta 8. I don't have any previous backups.
I've tried restarting my Mac, resetting SMC and doing some cleanup with CleanMyMac but no luck. What can I do, preferably without restoring my system?

I was having the same issue, and I just reinstalled the beta by going here: https://developer.apple.com/download/ then clicking "Install Profile" on Catalina. Then went to software update, and it started downloading Catalina again. Everything's fine now (no hanging, dragging works, etc.).
