Character flickers in blueprint viewport

Hi there,
I’m having a problem in which a character flickers both in the viewport in the Blueprint and also when playing:

I’m fairly new to Unreal Engine, but I followed this tutorial with good results, even with more complicated 3D models and also using Mixamo. https://www.youtube.com/watch?v=Z0FCeXkCW4k&ab_channel=MullerDigital

I thought initially it could be something with the FPS, but the problem persists with both 24fps and 30fps.

I have done everything again following the steps carefully and it’s still going on. It could be perhaps something with my 3D model?

Any tips would be greatly appreciated.
