When Studio opens the Toolbox does not work and displays this error:

When you click the Toolbox button it shows this error:

 builtin_Toolbox.rbxm.Toolbox.Core.Components.ToolboxPlugin:109: attempt to index nil with 'Enabled'

This is a major issue because I cannot upload animations needed for my game or import my toolbox models.

i have encountered a similar error in Roact, which is found in my server logs around 2-3 times per day

my application is not using any Roact features, this is from the Roblox core scripts

Seems Roblox itself has been buggy recently, I’ve had so many issues with studio that I’ve lost count. Just got another one where I can’t dock widgets to the bottom of Studio.

I’m now experiencing this. Toolbox also forcibly appears docked in an undesirable location every time I test my game. Would be nice if somebody moved this to the Studio Bugs category.

this also happens to me when changing audio duration in toolbox filter

That’s an issue for everyone, it’s happening to me too. When you try dragging the time the toolbox closes and shows this:

I’ve also just encountered this problem!

I also have this. Making progress on my horror game is extremely hard with this glitch.


(tested on a flat terrain to see if it was just that game or all studio projects)

Getting this error myself. Happens all the time.

the same thing happens to me aswell its super long
edit: i made it shorter to it wont pe painful scrolling through this

having the same problem, happens when I try to upload an animation using the blender plugin.

this is still happening for me, over a year later. It happens in the new studio beta as well. If I try to publish more than 1 animation it will show up
