Save the crash log and submit it to Norm / support so he can take a look.
This occurs occurs when program is attempting to access outside the bounds of some data, such as beyond the end of a string. Sincerely, the real cause could be anything - i.e. a plugin update or not compatible with new release: when I’m facing those issue, with no apparently solution, just to be sure I downgrade to the previous working version app, uninstall all plugins/brics and so on I’ve got installed then update and reinstall plugins once at time to check if one of them is causing application crash.
Longest procedure, but most often works well.
