I've lost my windows and grub in general after installing Kubuntu 22. Here is my efibootmgr entries:
$ sudo efibootmgr -v

I added the GRUB_DISABLE_OS_PROBER parameter to my grub config and ran sudo update-grub as suggested in the article. This is my output:

Memtest86+ needs a 16-bit boot, that is not available on EFI, exiting

Its output will be used to detect bootable binaries on them and create new boot entries.
