There is a problem with the cryptomatte of Blender 2.80 downloaded in snapstroe.
I made a blender project named "TEST.blend",When using the BLENDER 2.80 of the snap store to open this project file, the object mask and material mask cannot be used, the asset mask can be used, but it is wrong. So I uninstalled the blender 2.80 downloaded from the snap store and downloaded a Blender 2.80 from the Blender website. When I open my project with this Blender 2.80, I find that the object mask, the material mask can't be read, the asset mask can be read, but it is wrong. Then I switched to the windows system, opened the project with Blender 2.80 and found that cryptomatte works fine.
