the package was deprecated. Maybe try a couple more rollback targets?
In my experience as soon as a package was deprecated, you can't rollback to any prior updates (since eopkg would always fail when trying to look for the missing package on the repo). And exfat-utils was deprecated in the last sync (I know because I tried to rollback myself when I encountered display issues and couldn't either because of it 😛).
If you could provide the info about any custom kernel parameters you might have (like I explained in my last post), that would certainly help others help you.
I also suggest you try posting the logs (through something like hastebin) that your system generates when trying to boot. I'm not knowledgeable enough to do deduce anything from them myself, but others on this forum might.
The logs that might help in your case would be the journalctl and Xorg logs.
To get journalctl: sudo journalctl -b -e > <journaltcl>, where <journalctl> (without the <>) is the path where you want to save the log so you can upload it here afterwards.
To get Xorg: cat /var/log/Xorg.0.log > <Xorg>, where <Xorg> (without the <>) is the path where you want to save the log so you can upload it here afterwards.
