Hi @lepmad,

May I suggest that you start by installing and running the iDevice Panic Log Analyzer?
This is a very useful tool when working with panic logs.

This is a starting answer, but if you have updates after running the analyzer post updates to the question or comment.
If you can (and if it's easier), update your question with images / screenshots from the analyzer, so we can see what it tells you.
How to add images to existing question.

This panic log indicates "i2c0::_checkBusStatus SCL is stuck low"

This is referencing an electronics protocol, i2c or more properly I2C, that the board uses for different chips to communicate. Without getting into too much nitty gritty, the "stuck low" part means that the voltage on part of this circuit is stuck in a low voltage state. So whatever communication is trying to occur, isn't coming through.

iPhones have a few different i2c groups. On the XS Max, i2c0 includes largely charging related items and one of the two rear cameras. The first thing I would think is the battery. Since it's a pretty common source of failure and a lot of the communication on this line is related to charging.
