Exact steps for others to reproduce the error
Crash.blend

select Plane and in the node tree drag the "Minimum Vertices" socket onto Group Input node to create a new input, you should get instant crash

Workaround

select Cube and in the node tree Mute the "A" Group node
select Plane and drag "Minimum Vertices" socket again
select Cube and unmute the "A" Group node

I can't reproduce the crash anymore, it has probably been fixed. If the problem comes back, we can reopen this report. Thanks!
