I am running Unity 2020.2.3 on an SSD. I have a fairly large project (6gb asset folder, 16gb library folder), so I do expect my editor to be slower than usual… but not to this extend. Here are some, but not all, examples:
- Sometimes when assigning components in the inspector, Unity freezes and shows a “Hold on” window with “InpsectorWindow.MouseUp” which takes around 30-40 seconds.
- Clicking the drop-down on a material to change its shader causes a freeze and loading bar “InpsectorWindow.MouseDown” of around 60 seconds.
- Saving the project - sometimes instant, sometimes freeze with “Hold On. Application.ExcecuteMenuItem” of around 30-40 seconds.
- Changing a variable in inspector - sometimes instant, sometimes freeze with “Hold On. Application.ExcecuteMenuItem” of around 50-60 seconds.
- “Hold On. Application.ExcecuteMenuItem” of around 30 seconds happens quite often when performing regular tasks in the editor.
This became an issue only recently. I can’t claim exactly when, but I am certain this was not a problem in earlier versions of Unity with the same project. Any ideas why this is and how to fix it?
Below is an profiler screenshot from clicking a dropdown to change the shader.
