Both CalDigit and Belkin each used to have two different TB3 docks on the Apple store (I see that is no longer true). I believe that Anker used to be sold for a while but is no more. There used to be a TB4 dock, but I don't remember which brand as it was expensive enough that we returned it when it didn't work.
I have the adapter you pointed out and it also fails.
In addition, I KNOW FOR A FACT that this broke with an OS upgrade because I have a precisely identical laptop that runs an earlier version of macOS and the dock works fine. And if I swap the drives, the failure follows the OS.
