Grub menu does not hide though GRUB_TIMEOUT=0

I'm running Ubuntu 22.04.2 LTS and have dual boot windows 11. I'm trying to hide grub menu while booting and automatically boot ubuntu as I have seen that can be done with changing GRUB_TIMEOUT to 0 in /etc/default/grub and run sudo update-grub but grub doesn't hide and sets time to 10 seconds. I am able to change the timer to be different even -1 but 0 does not work for whatever reason. I have also come across the solution that in /etc/grub.d/40_custom I should add at the end of the file: set default="0" set timeout=0 . While this works I'm concerned that when some error occurs I would not be able to get into ubuntu advanced options because it disables grub menu in the boot time so I decided not to use it.

Here is my /etc/default/grub:

# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.
# For full documentation of the options in this file, see:
#   info -f grub -n 'Simple configuration'

GRUB_DEFAULT=0
GRUB_TIMEOUT_STYLE=hidden
GRUB_TIMEOUT=0
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash loglevel=0"
GRUB_CMDLINE_LINUX=""

# Uncomment to enable BadRAM filtering, modify to suit your needs
# This works with Linux (no patch required) and with any kernel that obtains
# the memory map information from GRUB (GNU Mach, kernel of FreeBSD ...)
#GRUB_BADRAM="0x01234567,0xfefefefe,0x89abcdef,0xefefefef"

# Uncomment to disable graphical terminal (grub-pc only)
#GRUB_TERMINAL=console

# The resolution used on graphical terminal
# note that you can use only modes which your graphic card supports via VBE
# you can see them in real GRUB with the command `vbeinfo'
#GRUB_GFXMODE=640x480

# Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux
#GRUB_DISABLE_LINUX_UUID=true

# Uncomment to disable generation of recovery mode menu entries
#GRUB_DISABLE_RECOVERY="true"

# Uncomment to get a beep at grub start
#GRUB_INIT_TUNE="480 440 1"
GRUB_DISABLE_OS_PROBER=false

I would be really grateful for any advice as to why my grub menu does not hide. Thank you in advance

Does this answer your question? [How can I get my GRUB menu to be hidden, AND have the shift or esc keys show the hidden GRUB menu at boot time](https://askubuntu.com/questions/879881/how-can-i-get-my-grub-menu-to-be-hidden-and-have-the-shift-or-esc-keys-show-the)

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
