I managed to fix this problem.
I think the issue was that TobiiXR_initializer was called before SRanipal framework, so i had bad connection and sometimes the tracker didn’t connect.
This only happened in the build version though.
In the end I attached the Ranipal framework to an object and called the initializer later and now it works perfect with no connection faults.
I saw some other people also have the same problem like me, so I hope this will help others in future also.
Thank you for your reply 🙂
Kind regards
