Worked: Not sure...
Short description of error
On nodes that have that "target" field (like the UVMap node etc), when you choose something from the list and then remove it by clicking on the (X) sign, if you don't move the mouse and click again on the same spot, blender crashes..
Exact steps for others to reproduce the error
In the shader editor, add a UVMap node, choose the uvmap in the "target" list, then remove it by clicking on (X). And without moving your mouse (or at least dont move it outside the button), click again on the same spot. Crash.
Double click on the (X) does the same thing..
