Movement stops while playing level

Hi, I’m pretty new using Unreal Engine

I’ve made a first-person player actor for a project I’m working on. But I have an issue while playing any level: after a few minutes, the character movement including any input key or button gets locked and field of view gets reseted, which don’t allow me to continue testing anything and I end up by pressing ‘Esc’ to exit from Play mode.
This only happens to me using the player actor I made, so I’m sure I did something wrong. It looks like the actor just gets removed from the level (that explains why the field of view gets reseted), but I’m not sure and I’m a bit lost on how I can debug to find the issue.

Someone had the same issue? How I can check if my player actor is being deleted from the level?
