@Aravisian, thank you for your quick response. I've just watched my BIOS settings now. There is a entry that mentioned Type C ports in my BIOS and is checked on:
USB Type-C Connector System Software Interface (USCI) - checked
The kernel that Zorin 16 Core installed is:
eldontc@eldontc-zdesk:~$ uname -r
5.11.0-38-generic
Yes, the 5.11 has had some regressions, though. Have you tried booting into an earlier kernel?
Please see link above.

Sorry, I will try an earlier kernel
Is there any power saving setting enabled on the amd card ?
If you have the proper driver installed for AMD, and you are running the proper kernel version for support of your hardware that doesn't have the regressions that Aravisian speaks about.
Michel mentions if you have power saving enabled on the AMD card. You can install the extension bellow to allow you to change the power performance levels of your AMD GPU.
https://extensions.gnome.org/extension/1079/radeon-dpm-control/
For general disabling of power management, you can do so by entering the following commands.
CTRL ALT T to enter terminal.
xset -dpms
I did a downgrade to kernel 5.4, but the resume after suspension presents the same behavior. The wallpaper crashed and I couldn’t click on any app icons, the keyboard was not working either, and so on.
eldontc@eldontc-zdesk:~$ uname -r
5.11.0-38-generic
I am a bit confused... You said you moved to the 5.4 kernel, but you posted a uname -r that shows the 5.11 kernel still. Did you boot into the 5.4 kernel?
Please go here to where the crash log should be located. Its a huge file, with tons of text, I don't really know what to look for, maybe Aravisian does, but this is where its located on your drive. I hope this helps...
@StarTreker and @Michel I inspected my bios but there isn't entries for power saving on the amd card. I tried to install de extension dpm control, but I got one error.
@Aravisian Sorry, I did a boot after error and enter with default Kernel, the image was wrong. But I've tried with kernel 5.4.
Some extensions will not work due to a version incompatibility. Just click the X to remove it. Then go to this link and try this one. Sometimes extensions are trial and error.

Are you logging in on Wayland?
Try screenfetch, what does it say?
CTRL ALT T to enter terminal
sudo apt install screenfetch
Then once installed, type screenfetch
Please post results. Screenfetch also shows what kernel is in use, so I am just wondering what it says.
@StarTreker there isn't any file with crash in name or extension in my system. The directory /var/crash is empty
eldontc@eldontc-zdesk:~$ ls /var/crash
eldontc@eldontc-zdesk:~$
Well, looks like extensions are not going to work for you, sorry to hear it. I did all I could here. Sorry I couldn't help you solve the issue.
I don't know what is Wayland
