Assertion failed on expression: 'gForceReimports->empty()'
UnityEditor.EditorApplication:Internal_CallGlobalEventHandler()

2019.3.7f1

Changed the color of text in TextMeshProGui and then my gameobject is invisible, can't switch enable/disable on it.

in play mode it is always in disabled state and see the error above.

Getting this issue with 2019.3.2f1

This is a new 3d Unity project.
Then imported Photon2 - free

Get this error after import.
Assertion failed on expression: 'gForceReimports->empty()'

Here is a possible solution: https://answers.unity.com/questions/1632274/how-to-avoid-the-onvalidate-method-from-being-call.html

The issue is that when the Prefab contains a script that uses OnValidate, OnValidate is being invoked and that can lead to this error.

same Issue on Unity 2019.3.7f1, will try to catch the point when it happens....

Hi, I'm a total beginner, so I can only explain the context when I had the same exception:
Assertion failed on expression: 'gForceReimports->empty()'

I tried to add an empty script to a prefab and it showed this error.
When I remove the rigidbody of the prefab, it works. Infact the exceptions seems to be related to the rigidbody (gravity).

Is there any limitation for the combo Rigidbody+script+prefab?
