Hi, I really need help from you guys, I have a presentation in less than one hour and I just don’t know what to do, I’m a noob at both computer and gnome, so I don’t know if it’s an easy fix or something more problematic 
I reloaded the computer after the mandatory updates for Fedora. I can access the login page as usual, but after entering my password I just get stuck on a dark screen, no option to do anything. I tried ESC and ctrl/alt/del but nothing happens. Forced it to turn down and started again, but same issue.
What should I do? 
It might be difficult to find the cause so quickly, but one thing you can try from the login menu is after you click on your name, go to the lower right corner of the screen and click on the cogwheel icon. There you can choose between Gnome and Gnome on Xorg. If you click on Gnome on Xorg and continue to log in, the result might be different.
Thank you so much Olivier for taking the time to propose solutions, I really appreciate it!
I did as you said, but I got the exact same issue with GNOME Classic (I don’t have an Xorg option). What did work though was to press ctrl/alt/del when booting in, to choose which Fedora kernel to boot. I chose an older version, which worked and I could get in. This is good for my presentation at least! BUT, the problem is not solved as whenever I restart and try login in, I get the dark screen again if I don’t chose the older version. Is there any way you could help me with that by any chance?
This is great news, good to hear.
It seems there is a specific issue with the last kernel version in that case. Often times this will resolve itself when the next kernel (or one soon thereafter) arrives. If the previous kernel works well for you, you can keep using it for the time being.
If you prefer to boot with your currently working kernel by default for a while, there are settings you can use to enforce that. There are a few threads on the forums that describe the steps to achieve this, one of them is the one below:
If you do want to dig in further to find the cause of the black screen with the latest kernel, you can open a terminal and issue the command:
$ journalctl --since=today -p 3
It will show all the errors in the system log that were registered today. There might be clues visible that will give more information about the cause of the problem.
Thanks for the tips, I will try to change the default kernel for now then and hope for the best 
I also tried the journal, but the results are so long that I honestly had no clue where I could start looking. This is where I see the limit of me using Linux-distros, being a complete beginner is very tough sometimes!
Thanks again for all the advice!
Before retiring I worked with a very large software system that required a POSIX environment, which in practical terms meant Linux or macOS. In workshops introducing new users to the software we found it necessary to spend the first afternoon introducing linux using https://LinuxCommand.org (written before AI-generated click-bait nonsense captured the internet).
