Worked: idk
Short description of error
when using color attributes, blender crashes if there are attributes with type color but not on domain vertex or face corner

Exact steps for others to reproduce the error

select the default cube
go to object data properties, expand the attributes and color attributes panel
add an attribute in attributes panel, with domain face and type color

note console outputs

uilist_filter_items: Error, py func returned 1 items in filter_neworder, 0 or none were expected.```

add an attribute in color attributes panel, with domain vertex and type color
move the cursor around to trigger an ui update, crash
or start from 3.
switch to edit mode then back to object mode, crash

rna_AttributeGroup_color_length seems fine (return zero), but the iterator skip function rna_Attributes_noncolor_layer_skip seems to cause problems (it does not skip other domains)

We then run into the following:

1 ui_block_free_button_groups interface_button_group.c 55   0x5937be8 
2 UI_block_free               interface.cc             3447 0x592d1fd 
3 UI_blocklist_free_inactive  interface.cc             3514 0x592d4be 
4 ED_region_do_draw           area.c                   575  0x4f487c8 
5 wm_draw_window_offscreen    wm_draw.c                729  0x45c1b37 
6 wm_draw_window              wm_draw.c                881  0x45c2117 
7 wm_draw_update              wm_draw.c                1086 0x45c2759 
8 WM_main                     wm.c                     629  0x45bde26 
9 main                        creator.c                547  0x3d88c74

Will see what I can do.
