TBT3-UDC3 not working on 16" MBP running Big Sur

Have a16" MBP running BigSur with 2 SD Lenovo monitors. No matter how I connect them using a brand new TBT-UDC3, after one sleep cycle, one of the monitors will begin blinking on and off. Then occasionally the computer will ask me to log back in as if it’s been put back to sleep even though auto sleep functions are disabled. For reasons I can’t go into here, I can’t simply restart EVERY TIME this happens. I need a fix. HELP!

This is currently being resolved by a warranty covered replacement with updated firmware.
