Kernel panic. Can't boot to Clear Linux from today evening

I am running CL from memory stick. It was working fine till yesterday. Getting Kernel panic error today. Can not boot.

Please help.

I never used a memory stick, unless to repair or install linux. So maybe I am just saying something stupid. But maybe you can try to interrupt the boot pressing and holding the space bar. From there, you may select another kernel to boot the system. And maybe a system update solve the problem. I would do this in a regularly installed system. I am not sure if you can choose a different kernel to boot a memory stick though.

Not working. I tried space and then ESC. Nothing working for me. Be aware it’s legacy installation not UEFI.
