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

Thank you for your collaboration
Sorry, I posted the wrong screen. The correct is:
Have you tested your RAM?
Are you using a Swap Partition?:
The base kernel that zorin 16 was built for is the 5.11.27. If you are going to try another kernel i would start there. Zorin 15.3 had the 5.8 kernel...i wouldn't go back further than that since the Ryzen 7 would have minimal support, if any, before that.
Have you tried restarting gnome when you wake your pc? Do you have power management configured to shut off pci-e or your SSD's? Are the drives NVMe or sata SSD? This can matter in power management and returning from sleep.
I run zorin 16 on a Ryzen 7, 32GB RAM, two 1TB NVMe without the issue of system freeze after sleep. 5.11.38 kernel. It is possible.
Edit: you may have a gnome.
I would be 100% beside myself if this expression replaces "you may have a bug."
