"error: /boot/vmlinuz-6.6.9-amd64 has invalid signature" with secure boot on in Kali Linux

When I try to run my Kali Linux system with secure boot on, GRUB returns error: /boot/vmlinuz-6.6.9-amd64 has invalid signature. I don't want to turn off secure boot. I have followed the directions from here: https://www.reddit.com/r/archlinux/comments/10pq74e/my_easy_method_for_setting_up_secure_boot_with I used the command grub-install --target=x86_64-efi --efi-directory=/boot/efi --modules="tpm" --disable-shim-lock to reinstall grub. I am dual-booting Windows 11 with Kali Linux. I run an HP Envy x360.
