Trados Studio bug "cannot access a disposed object" doing a search after opening Studio

Opened a project in Studio 2017 SR1, editor view opens, then clicked Ctrl-F to Find.

Got an error alert. XML below.

Probably a race condition because after closing this error alert, Ctrl-F works OK.

Best,

Jon
