First, I’m surprised that you don’t have a support category.
I’ve been trying to install UB for hours. When it gets to the desktop, the only things that appear are the wifi logo, the keyboard settings logo, and the volume logo. Nothing else loads. I have downloaded and redownloaded the iso several times, I have tried both the 19.10 and 20.04 releases and got the same results. I tried three different methods ofr writting ios to a thumb drive. I even tried Ubuntu Mate 20.04. UM did not have any problem booting.
I’m using a Dell Latitude D630. I have never had any problem installing a distro until now.
