Short description of error
Grease Pencil 2.82 version file with Blur Fx is crashing Blender 2.83 while loading. I tested it with the Grease Pencil Branch, and it is also the same problem there.
Exact steps for others to reproduce the error
In the properties panel, try to slide the focus_blur parameters. Not all of them cause crash though.
