Something with grub must not be correct. I might try the full uninstall/purge and total reinstall of grub from Boot-Repair.
Boot-Repair cannot parse Windows BCD. Any entries in Windows are from EasyBCD, and you need to use bcdEdit or EasyBCD to edit BCD to remove extra entries.
You show these in UEFI menu.

Both of these are your Windows boot from grub, not sure why Boot-Repairs says recovery
Boot-Repair's entry
menuentry "Windows UEFI recovery bootmgfw.efi"
os-prober's entry
menuentry "Windows Boot Manager (UEFI on /dev/sdb2)"
You also are showing dual video. Do you control Which video it boots with? With nVidia you need nomodeset, but Intel usually needs other boot parameters.
