Samsung Galaxy S9+ SM-965F Critical fault of Camera

I’m still running the e.OS 2.0-t-20240514401453-dev-star2lte rooted.

Mostly the phone works fine, but a few hours after rebooting, the camera refuses to start and appears: “Critical error!”
This is only cured by rebooting the phone, but after some time, this error happens again.
The phone memory is not full, so it can’t be the cause.

Also on the screen itself for a second before the screen turns off, sometimes there are horizontal stripes like ripples on old TVs of the 80s, 90s.
I think this is some kind of software error.

Has anyone encountered similar problems or not?
Thanks in advance for any ideas and thoughts on this.
Thank you!
