Out of a sudden, it just happen (need help)

Hi Guys, I am not sure what happen to my unity project, really need help

I work with my project for quite some times, my character have several animations, and all work perfectly, just today when I work with my games, all my animation just stop working, the character default animation should be running, but it just stop in 1st frame. Just the pose and it won’t continue play the others frames.

And even the other scene function with itween movement all have disable to run/move.
I wondering am I have accidentally shutdown anything for the animation or something else, I really can’t figure out what have happen. It just stop working suddenly. Anyone can help and tell me what have happen…

Read through the log file. Unity will almost certainly be telling you something. If no warnings or errors appear, then try debugging the script code.

I just solve it, after a lot of research and debugging, I found out that my timescale have been set to 0 permanent, I have no idea why my timescale is set to 0, it make me wondering is there any shortcut key will lead to timescale = 0,

what I do is, go to Edit > Project Settings > Time > timescale set to 1 , then all the problem solve
