System Information
Operating system: Windows-10-10.0.19043-SP0 64 Bits
Graphics card: GeForce GTX 970/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 461.09

Blender Version
Broken: version: 3.1.0, branch: master, commit date: 2022-03-08 18:16, hash: c77597cd0e , 3.2 broken as well
Worked: Blender 3.0 release
Caused by 7e712b2d6a

Exact steps for others to reproduce the error

open bug.blend, you should see blue cube
run the script, which should set "Red" Group Output as active and Cube should change to red color, but Green is set instead
you can see in the System Console that bpy.data.node_groups["A"].nodes["Red"].is_active_output is still False

Works as expected in 3.0

Also changing active Group Output by clicking on it in Shader Editor and running script right away is giving wrong result as well.

Hi, thanks for the report. I can confirm on latest master.
This is very similar to the other report which was fixed last week- #96292 (Unable to set active material output node using Python)

@JacquesLucke hi, any thoughts on backporting both the commits for corrective release?
