My USB ports work but show connection speed as 480 Mb/s which is USB 2.0 standard, not 3.0.

Look at this, maybe it helps.

I've found the reason. In my case, it's wrong language layout. My password is based on Latin symbols while macos offers my local language on logon page. And because we used to get proper layout, we don't check it and type wrong pass.

Disabling SIP aint a solution, either...

When it happened I just turned my Mac's power off and then back on. That helped.
Oh, I've got it. There's a little mess. 19A546d is public beta 6, but developer beta 7 😉
I never had panic on Beta 6 either, only on Beta 7. But on the previous beta my AirPlay speaker got network lost every 30-60 seconds, and that made it impossible to use.
Right after Beta 7 installation I tried sound output to AirPlay (which got some problems since Beta 6). Switcher in taskbar showed ability to use device (Philips AD7050W) but didn't let me enable it. After the third click on device choose option I've got kernel panic:(here I tried to submit the log of error but suddenly got "The message contains invalid characters").

#1 - AFAIK, yes. At attempt of data transfer from Catalina to Mohave you'll get an error "Update needed" or something like that.

This message just means that if you accidentally got installed some application into your root (Macintosh HD/*), instead of "Programs" or dedicated folder on Macintosh HD - Data, it will be deleted on Catalina update. And that's fine because the alternative way of deleting it requires, to say, some efforts: https://forums.developer.apple.com/message/371233#371233
1. Disable SIP (recovery mode, csrutil disable).2. Restart.2. Mount drive for read and write (sudo mount -uw /).3. Assign rights for read and right ([sudo] chmod - R 775 /your\ folder\).4. Delete it ([sudo] rm -rf /your\ folder\).5. Restart.5. Enable SIP (recovery mode, csrutil enable)."sudo" in square brackets means it may be required (like in my case) while others report they managed to get result without it.
