yes i figure it out so i am confused now what to do i upgraded the whole system just now and rebooted and nothing change the error still
ERROR: Missing 6.3.4-arch1-1 kernel headers for module rt3290/2.6.0.0rev1 and i even installed the linux-lts with pacman -S (dont judge me ) and now have 2 booting kernals lol i kinda like it but back the main subject how to fix it 
Post
pacman -Q linux
ls /boot
here
pacman -Q linux
linux 6.3.9.arch1-1
[nobodyknows@hp-nobodyknows ~]$ ls /boot
intel-ucode.imgi will try reinstall the whole system freshh omg frustrating
ok after reinstalling system with the online installer and linux-lts i tried installing AUR repository and the same problem showed which is deprecated but when i tried installing nvidia didjt give the error and install works great but got issue where bumblebee didnt detect my nvidia driver how to fix and for the bluetooth issue i actually giveup maybe if anyone could tell me how to make btusb kernel load as system boot may fix it other than that i will keep it broke not working
It looks like you have a miss match some how. See if this kernel is installed and uninstall it. When you installed the 470xx drivers did you install it like this,
yay -S nvidia-470xx-dkms
This should pull in the package nvidia-470xx-utils
Check if the correct version of utils is installed
Then you would also install the settings if wanted or needed.
yay -S nvidia-470xx-settings
Then you check if nvidia drivers are installed correctly
inxi -Ga
You needed to fully upgrade the system first as i told you before because there have been a huge number of updates including firmware and the kernel.
yay -Syu
Or
sudo pacman -Syu
Then when things are right and updated you try to get the bluetooth working.
Edit: If you reinstalled it should already be totally up to date. So this is why i suggest it may have something to do with the nvidia and dkms?
@MrNobodyknow
I know you said you have given up on the bluetooth but here is some more info.
the nvidia error got fixed after fresh install of the system with online installer get fresh updated except the linux kernel which i am getting update now(its looks my region getting the updates after like 3 hours from maybe) i installed nvidia using nvidia-inst not actually by it the script gives me the needed command to install them and setup (based on the nvidia aur which helped me alot) correct command 
and works fine then install bumblebee and it looks nvidia not having a problem in the installed dks or utils but when i run this command the output is
optirun glxgears -info
[ 1697.250476] [ERROR]Cannot access secondary GPU - error: [XORG] (EE) No devices detected.
[ 1697.250502] [ERROR]Aborting because fallback start is disabled.is there any idea to fix it
the output of “inxi -Ga”

i am looking at it the aur package actually autoblacklist my wifi which is rt2800pci but the problem its not actually installing because of the deprecated error
and the thread is in 2015 which is the same year it the AUR get the last update so at that time making it work wasn’t an issue 
haha
Edit: i will try the " rtbth-dkms" AUR again but this time i will try to load it my self and with and without blacklist for my wifi adaptar but i thinks its not gonna work but i will give it a try
I don’t think i would use bumblebee. I would try optimus-manager or envy control or prime? There are no settings in the Bios for integrated, dedicated or hybrid?
Edit: It is rendering on the Intel graphics.

no there is no nvidia settings in bios or dedicated gpu and yes running in intel stil figuring out how to work with nvidia ok so i will try optimus-manager and also for the bluetooth i found this
[Solution] https://www.invik.xyz/linux/RT3290-Bluetooth-on-Arch/
which actually really helpful and may work (but lets not give big hopes :
and also found this yt video
https://www.youtube.com/watch?v=NURmhQpaVWc
which uses same laptop so hope it works
Yes i did see this and also not sure if you checked as asked in the above posts if bluetooth was running?
systemctl status bluetooth
Edit: Hope that info you found helps getting it working.
i told u previuosly that when i test the bluetooth i already aware to check status and else and always sure its running because as i said i need to load the btusb manually because if i didint bluetoothctl withl not work and systemctl status will give
sudo systemctl status bluetooth
[sudo] password for nobodyknows:
○ bluetooth.service - Bluetooth service
Loaded: loaded (/usr/lib/systemd/system/bluetooth.service; disabled; preset: disabled)
Active: inactive (dead)
Docs: man:bluetoothd(8)
if i load btusb and systemctl start btusb the service will work fine
Edt: yea also as i mention btusb i think i must load it even if i used the rtbth-dkms right btusb for bluez nad bluez-utils so i must always load it ?
inactive because i didnt load btusb yet waiting for the upgrade of system to finish then installing the AUR and start testing
It shows inactive. You need to enable it!
sudo systemctl enable bluetooth.service
Edit: btusb should automatically load. 
i am not sure but its never gets automaticly loaded i always load btusb manually idk why the reason i will add it to modprobe.d manually after this
You can add both in the modpprobe.d conf file.
haha thanks alot i solved it the “rtbth-dkms-git” AUR solved the problem haha now lets fix nvidia wish me the best
EDIT: i installed optimus-manager but how to test if it works?
ok nvm got it works haha thanks alot <3 u made my day
Finally success! So when you switch to Nvidia and run inxi -Ga it should show you that it is rendering on the nvidia gpu!
