While updating my system to the latest version, it reportet that there were conflicting nvdidia packages. I didnt thaught much about it and continued. After I rebooted its only showing this: /dev/nvme0n1p2: clean, 2770599/31244288 files, 91246049/124948550 blocks
I can still access TTY3 and tried reinstalling the nvidia drivers, but it didnt do anything.
Sorry if this is just a stupid question, Im fairly new to linux.
kernels 517 and 414 are eol - end of life, i assume you were running the 5.17, thats why you are stuck, so reboot, and select the 5.15 in the grub menu, then uninstall the 5.17 and the 4.14, and install the 5.10 as a backup kernel
you dont uninstall them from grub, you just select the 5.15 boot with it and then from desktop you uninstall the eol kernels, either via manjaro settings, or via commands: sudo mhwd-kernel -r linux517 sudo mhwd-kernel -r linux414
