Opening any server in Object Explorer causes SSMS to shutdown with error log showing issue caused by RedGate.SQLSearch

When I open a server in Object Explorer, it appears for a few moments, then SSMS just shuts down with no error message. Doesn’t matter whether I open via connection explorer or registered servers; I can open a query window, connect to a server, and execute commands, so I am not completely dead in the water.

All my SQL Prompt/Search extensions are fully up to date

Error shown in Event Viewer:
