these days very slow to calculate routes and crashes

[Nick Carthew]

Not for me, everything is working as it should.

It's been slow for me on occasion, as in minutes to figure out a route. I believe this is because I have selected many avoidances, and it's a long route.

Not only these days.
In general calculating is fast enough. But from time to time calculating a new route after moving, adding or deleting a waypoint takes forever. Pressing F5 most of times solves this issue for that moment.
