According to the owner's manual of your 2022 Ram 5500, the location of the fuse for the running lights is F29. This is a 20 Amp Blue fuse. I recommend checking your manual to verify this information.

If the fuse is not the problem, I recommend checking the ground connection on your trailer and vehicle wiring harness. Make sure your ground connections are secure on a clean, bare-metal surface. This is often the issue when one function is not working correctly with trailer lights.

I have attached a helpful troubleshooting article for your reference.
