I am unable to reboot successfully after recent updates that first took me from 5.4.0-48 to 5.40-54, then after ran a repair from the Grub menu, I was upgraded to 5.4.0-65. Neither of the last two boots successfully. I am currently able to fully boot if I choose 5.4.0-48. I checked repositories but am not seeing anything unique except a few "ENTIRELY UNSUPPORTED" bionic repos. Although I have an AMD graphics controller, I do not recall installing any specific drivers.
I do recall that the last set of updates did not install and the OS kept getting stuck. I had also tried to install two free word processing apps from App Center which kept hanging as well.
Can someone help me figure out what could be going on? Thanks in advance for any suggestons!
