Upon a couple more tries, I found out the Layer Panel is not updating after importing. I tried to create new layers and after a couple more clicks, rhino crashes

Hi Wiley -

Please check if the current version of Rhino 8 - 8.28 - also behaves as described.

@wim

I can confirm the bug is still happening at SR28

Hi Wiley -

This sounds file-specific. If so, please upload the file from https://www.rhino3d.com/upload/ with reference to this thread.

Hey wim. it happens again today. in another file, the Layer UI crashes again.

I don’t think it is file specific. It happens when the file size is large and there are a lot of geometries.

After restarting the Layer Panel, it works again, like below

The problem happens to me 10-20 times a day. (this issue is quite unbearable)

Usually the Layer Panel crashes after rhino does some heavy operation.

Hi Wiley -

To get this fixed, we need to be able to reproduce that first.
