RTSP only stable when stream open in mydlink app

[fightforlife]

Hi there, I currently use two of these cameras via RTSP and go2rtc in HA.
For me the stream of the cam in HA is crashing every few minutes. Sometimes it heals itself, sometimes I have to reload the page.
I noticed that when I have the official mydlink app running and watching the stream the crashes disappear.
Does someone have an idea to block mydlink and still have stable RTSP?

Since we now have root access, it should be able to disable the mydlink stuff without blocking it from the outside.
