- Since you play on multiple platforms, it'd be really helpful to confirm what kind of system you were using, at the very least?

- Have you tried this on a vanilla client? (no plugins)

Have you been able to capture a recording that has the broken FOV?
The next time it happens, type:
/set fov
and report what it displays.

I don't experience a freeze while jumping in but I too get a messed up FOV when I jump in, it's a zoomed in view which I fix by just pressing 'i'(the zoom key). This is on both PC and mobile. I think the controls were inverted too.

Iirc I tried to change my ship view on mobile while I had the messed up FOV and my ship appeared inverted too, so nothing's happening to the controls but the views just changing by 180°.

Ok, I found the FOV problem, thanks.
