I hate to say but this thread gives me comfort that: a) it’s not just me, b) it’s not my particularly unfortunate combination of hardware, and c) I made the right call to permanently retire my Caldigit TS4 and rely on my Lenovo ultra-wide monitor’s ports.

Learning this lesson (on the unreliability of systems using a very expensive docks) cost me over $1200 in chopping and changing hardware in the last few years.
