Issues with part manipulation, keybinds, and object pasting in Roblox Studio

I’m experiencing multiple bugs in Roblox Studio that appear to be related to the new Solid Modeling Revamp beta feature. These issues impact essential building tools and editing functionality and happen inconsistently but frequently:

  • Paste does not work (Ctrl + V)

After copying an object using Ctrl + C, attempting to paste it with Ctrl + V does nothing — the object doesn’t appear, and there’s no error message or feedback.

  • Delete key doesn’t respond

Pressing Delete or Backspace on a selected object often has no effect. The button disables both for the BACKSPACE key and in the right mouse click menu.

  • Negate/Union (solid modeling) buttons disabled

Sometimes when I negate a part and try to union it with another, the operation doesn’t work the buttons are greyed out and unclickable.

  • Buttons re-enable temporarily

If I click on a different part, the solid modeling buttons (e.g., Union, Separate) briefly become enabled again and may work for a few seconds but then they disable again after a short time. During this disabled state, I’m unable to:

  • Perform any solid modeling actions

  • Delete parts

  • Paste anything

This behavior is very disruptive and makes Studio hard to use effectively.

Reproduction Steps
While the issue is inconsistent, this is the general workflow that exposes it:

Open any place (even an empty baseplate).

Insert multiple parts.

Try to negate and union parts → buttons often disabled.

Attempt to delete selected part with Delete/Backspace → nothing happens.

Copy and paste part with Ctrl + C / Ctrl + V → paste fails.

Select a different part → buttons may briefly enable.

After a few seconds, buttons become disabled again and features stop working.

A simple .rbxl file isn’t needed — this happens even in new, empty places.

System Information

  • CPU: AMD Ryzen 7 5700X (8 cores, 16 threads)

  • GPU: NVIDIA RTX 3060

  • OS: Windows 11

Expected behavior

With the Solid Modeling Revamp enabled, I expect Roblox Studio to retain the full functionality of:

  • Solid modeling tools (Negate, Union, Separate, Intersect)

  • Core editing shortcuts (Delete, Ctrl + C, Ctrl + V)

EDIT:
THE ISSUE STILL PERSISTS EVEN IF THE BETA FEATURE IS DISABLED.

This has been happening to me occasionally for a few months with all type of instances but has gotten much worse as of yesterday.

It now seems to happen every minute or so.
I’m unable to copy, paste, delete, clone, etc. anything until I manually select and deselect a few random things in the explorer.

I’ve noticed a few times when this happens that a part I had selected previously appears selected in the explorer, even though I have something different or even nothing at all selected at the time.
This apparent failure to deselect things is probably why manually selecting objects fixes it temporarily.

Can confirm I’ve had issues with everything listed here for the past few days, along with often not being able to ungroup models or to duplicate instances.

I have absolutely zero ideas on any reproduction steps, but this issue is extremely disrupting and I’m honestly surprised this post has attracted so little attention.

I’ve never had the solid modeling improvements beta enabled, if that matters.

It seems to be related to either Next Gen Studio or Next Gen Explorer. Selecting the object in the explorer window does allow these actions, but selecting in the 3D view does not. This is wildly infuriating and completely ruins development. I have no idea how this managed to make it into a release.

Myself I have and had both disabled (as seen on the screenshots by the way) and yet the issue is there. It has to be related to something niche, however, since this issue is too annoying to have so little feedback.

This really isnt acceptable from a billion dollar corporation, studio is unusable for building for anyone experiencing this.
