What is mesh quality before you start your simulation? Please check quality in Fluent.
What are your dynamic mesh settings? Which models you are using?
If possible, insert some images as well to explain problem in detail.

Mesh quality looks ok.
Is it hex mesh?
Can insert image of mesh scale info in remeshing panel?
Are you using any udf?
Please check following video which may help you.

In Remeshing, please use min length scale as 0.0001 and max len scale as 0.015.
In smothing, please use 100 iteraions and use All for elements.
Why do you have separate cell zones?
If this does not solve your issue, then we will need to see dynamic mesh zones.

Again below error came. but now i can simulate at second time step.

"Why do you have separate cell zones?" i don't aware of this. mesh file send by senior

Can you please insert image of your dynamic mesh zone settings.

It looks ok. What is symmetry zone?
Is it 2d o r3d?

Sorry its not clear to me about symmetry zones. Please explain your boundary zone names and their position in detail.
Also which models you are using?

As ANSYS employee, we can not download attachments. So please explain with inserting images. I know it will take some time, but we have to go with legal directions given to us.
