i really dont know how, the only thing i can think of, is to add the ibt parameter, since you are using nvidia+intel, and the issue happens only on the newer kernels:
sudo nano /etc/default/grub
and inside this line: GRUB_CMDLINE_LINUX_DEFAULT inside the quotes add this parameter:
ibt=off
dont remove anything, just add it to existing parameters, save the file with ctrl+x, press Y, then enter;
update grub:
sudo update-grub
reboot and select the 6.1 kernel and see if you can boot with it
