Actor transform not working when I run sequencer and simulation in existing project

[DevilMInd666]

I have a simple scene with sequencer and a mixamo animation using UE 5.2.1. I have followed following steps:

1. created a new Basic new Level
2. Imported fbx file in level.
3. Created level sequencer and add location keys for fbx from Point A to point B
4. Checked Simulate and Pressed Play Button.
5. Pressed Play in sequencer.

I dont have any issue on newly created project. But, the fbx doesnt move in my existing project(the project was created around 2 months ago in UE 5.2). I have checked my world settings and project settings. They are identical. The fbx is also same and I have nothing on the level except a basic plane. Could anyone set me on right direction? I dont understand what difference is there in existing project and new project.

never mind. I ported all my existing assets to new project and started working there. Wasted too much time on this.
