currently solus is using linux 6.3 as the linux-current package, is it fully updated?, if so you maybe booting from an older entry at boot time.
Could you show us what does sudo clr-boot-manager list-kernels
brings back?, my system keeps older entries from previous versions of the kernel, being current or lts, so maybe it's that your problem?
as an example of what i mean:
sudo clr-boot-manager list-kernels
