I did disconnect everything, put it all back together, and check the connections.
Thunderbolt 4 docs are still insanely expensive and I can’t afford to replace it right now, but I will keep that idea in mind. Your comment made me think about that side of things and I did come up with something else I’m going to try. My laptop only has USB C/Thunderbolt 4 connectors, but it has enough that I could connect everything directly and bypass the dock. If that works I can use it that way until I can get another dock.
