Ahoy,

I can't understand why you would get that error, can you tell me when exactly this happens, and on what Unity version?

Hi @Demigiant, thanks for the answer!

I added the DOTween component and hit the play all animations (just for testing!) and UI was got ugly and after I clicked the Stop animations. got this error every time. make sense?

by the way, I reinstalled and import the package and the problem was solved!

Ouch, I just managed to fix it. I made a silly mistake where, if you press the "play/all" button in the preview but there's no DOTweenAnimation set (meaning an empty DOTweenAnimation), it will cause errors. Will push it in the next update, apologies
