I updated the bios, tried to install with and without intel driver and change the display manager but the black screen is still here.
I will try to install endeavour with the offline installation
I suspect that it will not help…
If the problem continues, we need more logs, like
cat /var/log/Xorg.0.log | eos-sendlogsudo journalctl -b -0 | eos-sendlog
from the installed system, after trying to log in.
If you can’t log in, you can use either the USB installer, or the TTY (press e.g. Ctrl-Alt-F3 to get to a TTY) and run the commands.
With the USB installer, to get logs, you will need this info: https://discovery.endeavouros.com/system-rescue/arch-chroot-for-efi-uefi-systems/2021/03/ (assuming you have an UEFI system).
Ok, so I installed endeavour with the offline installation, it’s work I can boot but after updating the system and reboot the black screen is back
Run grub-install after updates before reboot?
I did the grub-install after reboot with a live USB, I don’t know if it makes a difference
The new iso should not be a problem. However, we saw a lot of problems with grub update couple of weeks ago. It is necessary to run the command before rebooting, else necessitates a chroot and fix it there.
This explains the fix. Still surprised in your case, I did not have any problems with updates and reboot with new iso…
Also see some blacklisting of Nvidia, did you do that? Or was that automatic install.
module_blacklist=nvidia,nvidia_modeset,nvidia_uvm,nvidia_drm,pcspkr nouveau.modeset=1 i915.modeset=1 radeon.modeset=1 nvme_load=yes
Also your boot parameter is entirely different than mine. Perhaps try install first without encryption, or if you do run the grub-install before reboot but right after update if you can. Curious if it is really grub related.
I reinstalled endeavour with the offline installation, update, grub-install and reboot but the black screen is still there.
I will try to install endeavour without disk encryption.
I did not change anything about nvidia or boot parameter.
I tried without disk encryption and the black screen is still there
I don’t know what to do 
How about the logs mentioned above? 
I can’t upload them, I don’t have internet connection when i use chroot and i can’t edit /etc/resolv.conf, maybe i’m missing something
I assume you do have internet connection with the USB installer, right?
Then arch-chroot into the system, redirect the outputs to a file, then exit arch-chroot, mount the proper partitions, and then run
cat "/path/to/the/file/you/just/created" | eos-sendlog
cat /var/log/Xorg.0.log: https://clbin.com/dD5kp
sudo journalctl -b -0 : https://clbin.com/fEZPf

[ 6.579] (EE) AIGLX error: dlopen of /usr/lib/dri/i965_dri.so failed (/usr/lib/dri/i965_dri.so: cannot open shared object file: No such file or directory)
[ 6.579] (EE) AIGLX error: unable to load driver i965
The second log is empty…
yeah i know but when i cat it it’s empty
this is because system is booted from liveiso…

as it shows it can not load unable to load driver i965 what is strange… but could be some leftover from latest removal of older driver from mesa and unrelated…
Because I would bet the device is not some 10y old hardware…
It could be simple an issue with the current kernel… as X is working on the ISO with an older kernel… but we had also mesa update lately… so could be both… but it worth try is to install LTS kernel:
sudo pacman -S linux-lts linux-lts-headers and boot with this one
(do not forget to run sudo grub-mkconfig -o /boot/grub/grub.cfg)

Maybe try these kernel parameters in the default grub command line and update grub with the proper command
i915.enable_rc6=0 i915.enable_psr=0

yes iris gpu i remember a lot users having issues but it was some time ago…
https://discovery.endeavouros.com/intel-gpu/intel/2021/03/
I was also thinking about this! But didn’t want to suggest it, isn’t it that the new iso requires some additional fix because of grub when one installs another kernel? Is it just running grub-install?

only regenerating grub.cfg this is needed after adding removing anything to the boot process
like options to grub kernel line or adding and removing a kernel.
sudo grub-mkconfig -o /boot/grub/grub.cfg
