Scene composer freezes the SDK

First of all, this project is for school, and I need a speedy response. This is my first time using jmonkey. I need to make a first-person maze game, and to do that I need the scene composer. But every time I try to open a scene, the SDK freezes, and does absolutely nothing until you close it in task manager. When I launch the SDK, I get this text in the bar near the bottom of the screen:

If someone could come up with a solution, It woud save my 3rd quarter grade. Thanks.

Update to 3.2.1-stable and hope it fixes the problem
The issue is related to a problem in jme in combination with amd gpu’s so if nothing works, maybe you have access to a pc with another gpu

I can’t update the SDK on the school laptops, but it works on my home computer. This will work, but it would be convenient if I could use the scene composer on the school laptops.

You can download the portable Version (the zip) on the school Laptop

I know, but the IT manager has blocked the installation of any software without his permission. I can edit files, but that’s it.
