Upgraded to 11.5.1 - issue persists. 😠

Glad it worked for you 🤞🏻 I also have a CalDigit dock (USB-C Pro), but no HDMI ports., just DP. Actually 2 of them (home & office) and my laptop keeps crashing, even if they are not peripheral plugged in. I also borrowed 2 docks from a colleague - Microsoft one & StarTech - same results :( All started after upgrade to macOS 11.3.1 so I think macOS is the culprit. Upgrading to 11.5.1 haven't resolved the issue yet.

Just my 2C. Same machine same dock ( actually 2 - one at home, one in the office). Same "solution" from apple - reinstall + restore. Didn't work. They suggested also that I downgrade to 11.2 (which when I DID NOT have problems) and then reinstall all my apps... Which is not a practical solution for me.
