Studio gives error when attempting to union objects

[ProgrammerOnCoffee]

When I attempt to union three specific objects in Studio (place file below), it will give an error (error code -11) and tells me to report it.

After the bug, my entire computer (system information below) started being extremely slow to the point where simple tasks such as changing tabs or windows took 30 seconds or more, even after closing Studio.
I had to shut down my computer entirely to make it stop lagging. I am no longer experiencing the lag, and unfortunately I don’t have a microprofiler dump from when I was.

This only happens in Studio
This started happening on April 11th at about 10:05 AM EST
I do not have any plug-ins

Repro
(Consider saving anything you have open in case your PC starts lagging like mine and you have to shut it down)

• Open place file (below)
• Go to the “Model” tab
• Select the three objects (Part, NegativePart, and NegativePart) and click “Union”

Studio will then give an error and say to report it; PC may be extremely slow afterwards
Bug occurs 100% of the time.

Me and another person was having the same issue yesterday

This happens commonly with the new CSG beta feature. Disable it in the Beta Features menu.

@ProgrammerOnCoffee / @TaylorDev_RBLX,
We took a look at this repro file and did not find the issue reproducing anymore. There were a number of stability fixes to CSG that went in over the last few months. If you are still able to reproduce this, please open another dev forum bug report and drop us another RBXL file and we would love to chase it down!

Thanks
