From GRUB menu try to boot an older kernel. -- on grub, press 'e' when the list of kernels show, look for the line with:
quiet splash , remove both and add the number 3 at the end, then press
Ctrl + X

Alternatively, don't modify the line and just hit enter on the selected kernel, then drop to a TTY using Ctrl + Alt + F3
sudo dkms autoinstall
sudo dracut -f --regenerate-all
reboot
If any of these steps produce an error, note it and consult our Discord for further help.
