System Information
Operating system: Windows-10-10.0.19041-SP0 64 Bits
Graphics card: GeForce GTX 1060 6GB/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 456.71

Blender Version
Broken: version: 3.0.1, branch: master, commit date: 2022-01-25 17:19, hash: dc2d180181
Worked: unkown / never(?)

Short description of error
If some attributes are present on a mesh (occured with String data for edges at least) blender crashes if this data is viewed in the Data API outliner view while also being in Edit mode / chaging to edit mode

Exact steps for others to reproduce the error
Add custom mesh attributes, navigate to these in the Data API outliner view and switch into Edit mode in the 3D view.

note: attribute layers being empty in editmode is kind of expected (see comment below), but of course, should not crash

In D11998 #309317, @brecht wrote:
A consequence of this is that attribute.data will be empty when in edit mode, since custom data is stored per element instead of a single array there. UV maps behave the same so that seems fine.

Data for UVs, vertexcolors etc. is also empty in editmode, but at least these seem to properly set the collection size to zero when entering editmode.
Will check on this.
