Came here via Google while debugging kernel panics related to external Thunderbolt 3 Display / CalDigit TS3+ hub. High-end 2020 13" MacBook Pro, 4 TB disk / 2.3 GHz i7 / 32 GB memory, Catalina 10.15.6.
Most expensive paperweight I ever bought, praying somebody has an update.
Have you contacted Caldigit support? They are quite responsive and have some troubleshooting steps.
