Worked:

Short description of error
When you set the active collection not by clicking on the text field but by toggling the "set active" icon in the "left column," Blender crashes. The same happens with "set active Scene."

Exact steps for others to reproduce the error
Go in the Outliner to the "Filter" pop-over; toggle "show left column"; add a new collection; click the "set active collection" toggle on the left.
