#1 Updated by Giovanni Manghi over 4 years ago

  • Priority changed from Normal to High
  • Category changed from GUI to Field calculator

Can you try with a new/clean qgis profile and no 3rd party plugins installed? thanks.

#2 Updated by Przemek Garasz over 4 years ago

  • Status changed from Open to Closed

Disabling the plugins alone helped. Then I enabled all the plugins one by one to see which one is it, and to my surprise, it turned out it's the Processing plugin.

A fresh profile does not crash with Processing enabled, so something must have gone corrupt in mine.
