Hi, I know I might be a bit late to this topic.
I have this exact same issue with the EXACT same graphics card RX 5500 XT.
And in short, Go into Safe Mode on Windows and uninstall the Graphics Driver in the Device Manager.
Use DDU (Display Driver Uninstaller) to make sure your system is clean of all the AMD Drivers.
Me and him are working at the moment to find the most stable driver.
