Today + Last week I updated to the latest version of Rhino 8
Version 8 (8.21.25168.13002, 2025-06-17)
(last week the number before).
When I start a new file no problem at all.
As soon I open one of the files I worked on, it crashes without warning.
When I disable solver no problem at all.
I enabled a lot of stuff and deleted some parts.
Then activated solver. And had to look at the coloured round cursor turning around. One file was opened after 30-40 secs.
Another I had to do a forced stop.
