BLOCKS 5.1.4
MACOSX VENTURA 13.6.4
I tell you that lately I have presented the following errors when working in the class editor.
This happens when I go to customize the classes and when I click on any option, the internal error window appears. This makes editing and work very difficult.
I attach images and the crash log.
