Your RX 5500XT supports Vulkan API. Vulcan is enabled on the GPU card from the AMD Driver.
Here is the specs for your GPU card from TechPowerUP: AMD Radeon RX 5500 XT Specs | TechPowerUp GPU Database
I am assuming you have Windows 10 installed and not Enterprise version. Here is the latest RX 5500XT AMD Driver for Windows 10: https://www.amd.com/en/support/graphics/amd-radeon-5500-series/amd-radeon-rx-5500-series/amd-radeon-...
So either you have a corrupt installation of the AMD Driver or it is out-dated. To check if Vulcan is enabled on your GPU Card, download and run GPU-Z and see if Vulcan is enabled. Here is mine showing Vulcan enabled on my Nvidia GPU card:
If it is not enabled than something is wrong with the installation of the AMD Driver.
Also you didn't mention what program/game you are trying to run which may not support Vulcan.
