Unable to boot except in Recovery mode
https://askubuntu.com/questions/1563512/unable-to-boot-except-in-recovery-modeI have been having this issue for months and I have now reached the stage where I may have to give up on Ubuntu. I can only log in via 'Recovery' and the resulting speed means that it's virtually useless to do so. I am 99.99% certain the issue arises from some type of conflict between my Radeon RX 5500/5500M graphics card and 22.04.05. I have tried every solution on the net that I can find (loading the recommended AMD drivers, updating, upgrading, editing GRUB four different ways (nomodeset, etc), reinstalling desktop, fixing firmware, Boot Repair, etc, etc.). Sometimes I can sort the issue but then every time I try to log back in - same issue. Since Xmas I have just been leaving the computer on after I last managed to sort the problem - no issues, the computer ran like silk. Then I got a message that updates were needed so I did that and rebooted, the problem returned. I know the machine can work properly so I really doubt it's a hardware issue and I don't understand why it reverts when I turn the computer off. I took careful notes the last time I managed a fix, none of that now works.
Grub is this:
GRUB_DEFAULT=0
GRUB_TIMEOUT_STYLE=menu
GRUB_TIMEOUT=10
GRUB_DISTRIBUTOR="lsb_release -i -s 2\> /dev/null || echo Debian"
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash amdgpu.dc=0"
GRUB_CMDLINE_LINUX=""
The odd thing is that when I run journalctl -b I get notifications that 'nomodeset' is preventing certain lines loading but as you can see I am not using it in GRUB. Just running "quiet splash" does not work.
Happy to list the output of any log required on demand.

Does anyone have an inkling of a suggestion as to what I can do??
