I’m going to take a guess that you put in your password for the “login” line. Easy mistake to make. At the first “login:” prompt you want to put your username i.e. “Liam” or whatever it is. Then after you hit enter it will ask for the “password:” and that will be your regular OM passsword (not a hardrive or encryption key). In other words the password you set up during installation.
But it sounds like just booting an earlier kernel solved hard part of the problem. That makes me think the problem was/is related to this other post:
and/or this new one:
When I fixed my own I saw the kernel change from kernel version 6.14.0-2 to kernel version 6.14.0-3 …
The best suggestion I have would be to post here the output of the command to get your kernel versions
rpm -qa|grep kernel
I’m not qualified to suggest anything further than that. You might try @stephane 's comment of getting getting a journalctl -b and posting it here so that it can be examined.
journalctl -b -1 > journal-no-boot.txt
That will create a text file called journal-no-boot.txt …Use dolphin and do a search for it then post it here.
Unfortunately I would have no idea how to make sense of it, but someone here should maybe be able to read it and tell you the best way to keep your machine running.
