I installed the 20.04 Gnome ISO this morning - direct to disk - not in a VM.
No issues during the installation but upon rebooting I couldn't get past the login screen. I'd enter my password and the screen would flicker and I'd be put back to the login page.
Switching to a terminal and looking at the Xorg log showed me that it was crashing.

Some googling lead me to a page which pointed the finger at gstreamer. Removed it and that resolved the issue.
I should point out that I elected to not download updates during the installation process, so maybe if I had done so, this issue would be corrected before I got to see it but I can confirm Xorg was crashing on a freshly installed, 20.04 right out of the box.
