Device crashes at some point after hitting Ride. Courses generally load up ("calculate"). If I press the X or the tick on the message about being near the start it crashes. Sometimes I get a short distance, but if I go off route it also crashes. Initially it crashed as the thing was "calculating" so I looked at routing settings and found that (for some reason) it was set to avoid ALL various road types. I changed this to just avoid toll roads which meant it just crashed a bit later in the process. I've tried various route versions incl from BaseCamp, from Strava and by converting a ride to a route and they all fail. I just have the one map enabled (UK OS 50k) which has worked in the past. I'm wondering about v9.50, but I can't find a way of reloading the version.
