after update my kali i can’t login to kali i put my username:password he crash with black screen and return back to lock screen agin any one can help me ?
looks like you didn’t use sudo apt full-upgrade command to upgrade your system
I ues it and i ues tty in Lock screen and still don’t work
if you don’t have any important data, then it’s easy to reinstall. We don’t know what you did with your system so that it broke. most of the people face the black screen issue after using the wrong command for upgrading their system.

i use this sudo apt update -y && sudo apt full-upgrade -y && sudo apt autoremove -y && sudo apt autoclean -y
I say this as someone with over 20 years experience administering Linux systems, when doing upgrades I would advise not using the -y flag, and not chaining commands together.
After you issue:
sudo apt full-upgrade
It will give you a summary of what it intends to do, including what it is going to add, and what it is going to remove. Run your eye over the summary and make sure you are happy with it, before typing “y”.
All you need is for one package (out of thousands) to be misconfigured for apt to make the decision to remove the X.org daemon or another vital component.
By not including “-y” you have the oppertunity to check what it is going to do.
Likewise with autoremove, don’t assume apt is going to do the right thing all the time, it might remove a library or other component you rely on.
I’m going to echo @serval and suggest you do a reinstall. It will probably take too long to figure out what went wrong.
