Camera blocked, but only in the morning.

I have been a happy owner of my MG4 since feb 23, and have been driving around 110.000km in it, without any issues.
But now suddenly i'm having a weird problem.
Every morning when I drive to work (about 100km), after 30 minuts all my assist systems shuts off, Lane assist, ACC, auto high/lowbeam etc. sign recognition still works thu. First i thought it was the sun, but it also shuts down during a overcast day.
On the way home from work everything works fine again, and i drive home without any issues.
This as been going on the past 2 weeks, its the same very day.
I have been drive the same road to work and home for over 2 years without any issues.
It starte when I was on holiday (2 weeks ago and it was extremly hot and the aircon was on full blast and on low.
Suddenly out of the blue the temp drop 10 degress and I drove into heavy showers, 10min. later all assist shutted down and never came back on until the next day.
And now im facing the issues where it shut off on the way to work. But works on the way home.
Anythought or idears?
Thank you

Edit:
I actually get a error messengs just before it turns of the assist system, something like: camera is blocked.....
And I'm on R63.

Check the terminations on your 12V battery - one might be a bit loose. Also your 12V battery may be on the way out - perhaps a new one is needed.

It sounds like the camera in the rear view mirror housing facing out of the windscreen is misting up. The camera housing isn't sealed to the windscreen, so in high humidity or with temperature differences while the rest of the windscreen clears with aircon or de-mist, it creates it own little humid climate within the housing and mists up either the camera or the windscreen aperture. It clears in time and the error go away and functionality is restored.

When it happens again can you stop safely, get out and look from the outside to see if the screen in front of the camera has misted up?
