Hello. This is the only place I've seen someone experience this issue as well, so I have to grab onto this thread. Today, I've installed Solus Plasma on my SSD while having Windows on a separate NVMe drive. I had trouble with trying to get Solus 4.3 to boot so had to resort to 4.1. After I got it fired up & installed without issues, I've rebooted the system for all the changes to take effect. To my surprise, the system does not boot anymore. It just gets stuck on a black screen with a blinking cursor in the upper left-hand corner, however I am able to change into another TTY session with the F-keys. Trying to update the system by doing sudo eopkg up. it gives me an error about missing file(s), especially metadata.xml. I am unable to do anything update-wise to the system as every similiar command to the one mentioned above results in the aforementioned error.
What could be the reason for it? Missing GPU drivers? Something not playing well with my mobo? The metadata.xml was related to Kross if I remember correctly
