As i saw from your GPU-z picture, it seems that you use one of the latest drivers from AMD.
Please remove it and use an older version for your card.
I personally do not recommend to use for RX400 and RX500 series the latest drivers, cause AMD do not improve anything in those drivers for this old cards.
The only thing they do eventually is to correct some games errors or glitches.
So i would suggest to use on older driver using the following procedure :
I would suggest to remove old drivers ONLY by using DDU.
This is a tool exactly for that.
You will do it in safe mode with the network disconnected.
After you restart computer (w/o network) windows won't be able to install auto the drivers due to the lack of network.
Now you will be able to clean install the drivers you desire.
As i said earlier DO NOT use the latest drivers, since AMD is known for ignoring the old video cards in the latest drivers. All they improve (actually they only correct) some errors in games reported by players.
So try to use a 2019-2020 version.
I would suggest the following:

After you finished reinstall drivers but before you put the network cable back on, you will block windows 10 to autoupdate.
To disable automatic updates on Windows 10 permanently, use these steps:
- Open Start.
- Search for gpedit.msc and click the top result to launch the Local Group Policy Editor.
- Navigate to the following path:
Computer Configuration > Administrative Templates > Windows Components > Windows Update
- Double-click the Configure Automatic Updates policy on the right side.
- Check the Disabled option to turn off automatic updates permanently on Windows 10.
- Click the Apply button.
- Click the OK button.
After you complete the steps, the system will stop downloading updates automatically.
However, the ability to check for updates manually will continue to be available on
Settings >
Update & Security >
Windows Update, and clicking the
Check for updates button to download the most recent patches.
Only now you can reconnect the network.
