weird camera shake

[Cr4zyFX]

Hello people,
I'm working on a simple text animation and I have a weird Issue I never had before.
The text animation looks fine in my viewport. But as soon as I start rendering, random camera shakes appear.

As you can see they only appear in the 2nd camera. I already tried making new cameras, but nothing helps.

I have checked everything and there are no keyframes. If I render it using cinemas standart renderer, those shakes don't appear...

I found the problem, an object that was behind the camera was set as a focus object. It wasn't moving but somehow still caused those little shakes.
