Question Graphics device is null. TMPro.TextMeshProUGUI:Awake()

while Instantiating a prefab that contains TMPro receives an error.

"Graphics device is null.
TMPro.TextMeshProUGUI:Awake()
..etc"

note * this happens only when I try to log in with google and cancel it and on cancel shows the popup that contains TMPro.

 

Unity and other SDK Versions that I'm using.
Unity -V: 2021.3.14f1
Firebase -V: 10.2.0
Facebook -V: 15.1.0
Google. -V: 1.0.4

 

Did you find a solution?

 

Yes found the issue
reason: "this happens to me due to not calling the TMPro on the Main thread".
Google sign-in was not on the main thread and when I received the callback and try to Instantiate the popup that contains TMPro give that error.

sol: try Google or any other third-party sign-in or any server query on the Main thread and never call TMPro rather than the Main thread.

 

Thank you so much.

Actually, my problem is that I'm in the development phase of a game and I give the user extra rights to continue the game after watching a rewarded ad. But the bounty ad is ending and the game is Graphics device is null. Stopping with error TMPro.TextMeshProUGUI:Awake().

Do you have a solution suggestion for this problem?

 

I solved this problem by making a delay of 0.2 seconds after closing the ad and after that I show the reward panel
