Thanks for the bug report. Please be careful to report only one issue per bug report.
When you have trouble with the USB not booting, that's usually a bad copy of the ISO on the USB or a slightly faulty thumb drive. Very common. Always have a different thumb drive handy to try.
If you want to stick with 20.04 instead then please try 20.04.4 (https://ubuntu.com/download/desktop) and choose a single issue to discuss, presumably the first issue you face.

I suggest the best place to start is with Ubuntu 22.04 (http:// cdimage. ubuntu. com/daily- live/current/). If you have trouble with that then we would like to know ASAP.
